性能

QuantiFast Pathogen +IC Kits enable simultaneous detection of viral RNA or DNA targets plus the supplied Internal Control over a wide linear range without loss of sensitivity when multiplexing (see figures Sensitive detection of Norovirus on the Rotor-Gene Q and High linearity and precision of singleplex and duplex detection). The protocol has been developed to run fast cycling experiments on most cyclers with high reliability (see figures "Sensitive detection of BHV-1 on the Rotor-Gene Q" and "Sensitive detection of BHV-1 on the ABI 7500"). Combined amplification of pathogen target and the Internal Control using the QuantiFast Pathogen +IC Kits increases process safety of the pathogen detection workflow by ensuring the correct interpretation of negative results (see figure "Correct interpretation of negative results").

QuantiTect Nucleic Acid Dilution Buffer, supplied with the kits, stabilizes RNA and DNA standards during dilution and reaction setup and prevents loss of nucleic acids on plastic surfaces, such as tubes or pipet tips. It enables reliable dilution of standards used to quantify viral nucleic acids, giving a wide linear range, from low to high CT values. The buffer ensures longer storage of standards without degradation (see figure "Reliable dilution and storage of RNA standards").

原理

To enable high process safety through the correct interpretation of negative results, each QuantiFast Pathogen _IC Kit contains reagents for multiplex, real-time detection of a user-defined pathogen target with the Internal Control. Amplifying control and target genes in the same reaction, instead of separate reactions, increases the reliability of gene quantification by minimizing handling errors.

QuantiFast Pathogen +IC Kits provide sensitive and rapid real-time multiplex PCR or one-step RT-PCR detection of pathogen nucleic acids on the first attempt (see flowchart "QIAGEN multiplex kits"). The optimized master mix ensures that PCR products in a multiplex reaction are amplified with the same efficiency and sensitivity as PCR products in a corresponding single-amplification reaction. The specially developed fast PCR buffer contains the novel additive Q-Bond, which significantly reduces denaturation, annealing, and extension times (see figure "Fast primer annealing"). A balanced combination of K+ and NH4+ ions as well as unique synthetic Factor MP, promote stable and efficient annealing of primers and probes to the nucleic acid template, enabling high PCR efficiency (see figure "Unique PCR buffer"). In addition, the unique formulation of Sensiscript Reverse Transcriptase ensures highly sensitive reverse transcription of viral RNA, while HotStarTaq Plus DNA Polymerase provides a stringent hot start, preventing the formation of nonspecific products.

操作流程

QuantiFast Pathogen +IC Kits provide a simple procedure for the detection of a user-defined pathogen and the Internal Control. They contain a ready-to-use master mix for the real-time detection of viral RNA (1-step RT-PCR) or viral, bacterial, and fungal DNA (PCR). There is no need for optimization of reaction and cycling conditions. Simply mix the supplied master mix with the pathogen assay (primers and probe) and the supplied Internal Control Assay and the Internal Control DNA or RNA. Alternatively, if the Internal Control has been added to the sample purification procedure, add RNase-free water instead of Internal Control DNA or RNA to the reaction mix. Then add your sample DNA or RNA and start the reaction on any cycler. The kit handbook contains optimized protocols for use with TaqMan® probes on a wide range of cyclers. It also contains recommendations for selection of dye combinations.

Each QuantiFast Pathogen +IC Kit includes the Internal Control Assay and Internal Control DNA or RNA for use as an amplification control via direct addition to the reaction mix. Alternatively, the IC can be added to the purification procedure to control both the purification process and amplification. For addition of the Internal Control to the purification procedure, highly concentrated Internal Control DNA or RNA (High conc.) can be ordered separately (see figure "QIAGEN Internal Control").

Correct interpretation of negative results.
Correct interpretation of negative results.
Duplicates of two concentrations of a viral RNA target were co-amplified with the Internal Control in the presence of different amounts of a PCR inhibitory substance (humic acid) on the Rotor-Gene Q. [A] No template controls (NTCs) serve as a reference for Internal Control signal. [B] Amplification of viral RNA target and Internal Control confirms successful amplification. [C] The Internal Control indicates the presence of a low amount of inhibitors. [D] Failure to detect the Internal Control shows the failure of the amplification reaction through presence of inhibitors.
Sensitive detection of BHV-1 on the Rotor-Gene Q.
Sensitive detection of BHV-1 on the Rotor-Gene Q.
Bovine herpes virus type 1 was serially diluted (100 to 10-4) and detected by either singleplex real-time PCR or by duplex real-time PCR in parallel with the Internal Control. Real-time PCR was carried out using the QuantiFast Pathogen PCR +IC Kit on the Rotor-Gene Q according to the supplied protocols and without any PCR optimization. The duplex reactions contained a fixed amount of Internal Control template. Each dilution was analyzed in triplicate; one replicate is shown for each dilution.
ID_0259_QFPathogen
Sensitive detection of Norovirus.
A Norovirus RNA transcript was serially diluted (100 to 10-5) and detected by either singleplex real-time RT-PCR or by duplex real-time PCR in parallel with the Internal Control. Real-time PCR was carried out using the QuantiFast Pathogen RT-PCR +IC Kit on the Rotor-Gene Q without any PCR optimization. Duplex reactions contained a fixed amount of Internal Control template. Each dilution was analyzed in triplicate; one replicate per dilution is shown.
Sensitive detection of BHV-1 on the ABI 7500
Sensitive detection of BHV-1 on the ABI 7500.
Bovine herpes virus type 1 was serially diluted (100 to 10-4) and detected by either singleplex real-time PCR or by duplex real-time PCR in parallel with the Internal Control. Real-time PCR was carried out using the QuantiFast Pathogen PCR +IC Kit on the ABI 7500 according to the supplied protocols and without any PCR optimization. The duplex reactions contained a fixed amount of Internal Control template. Each dilution was analyzed in triplicate; one replicate is shown for each dilution.
Fast primer annealing with Q-Bond
Fast primer annealing.
[A] Q-Bond in QuantiFast Buffer allows the DNA polymerase and primer to bind as a single complex, reducing the annealing time to a few seconds. In addition, the unique buffer composition supports the melting of DNA, reducing denaturation and extension times. [B] Without Q-Bond, the primer and polymerase bind sequentially to the template, increasing annealing time.
Successful Multiplex PCR-Based Genotypic Analysis without the Need for Optimization
QIAGEN multiplex kits.
QuantiFast Pathogen +IC Kits provide a simple procedure for quantitative, multiplex, real-time PCR. In contrast to current methods, the kits eliminate the need for optimization of the concentrations of primers, Mg2+, and Taq DNA polymerase, even for difficult assays (e.g., assays in which the copy number of the target gene is much smaller than that for the reference gene).
Unique Type-it Microsatellite PCR Buffer Promotes Stable and Efficient Annealing
Unique PCR buffer.
[A] NH4+ ions prevent nonspecific primers from annealing to the template. [B] Synthetic Factor MP, an innovative PCR additive, increases the local concentration of primers at the template. Together with K+ and other cations, Factor MP stabilizes specifically bound primers, allowing efficient primer extension by HotStarTaq Plus DNA Polymerase.
QIAGEN Internal Control illustration
QIAGEN Internal Control.

Simultaneous extraction and/or amplification of a pathogen target plus an internal positive control will rule out PCR inhibition or other problems that could give a false-negative result, leading to higher process safety. The QIAGEN Internal Control can be added prior to PCR amplification to provide an amplification control, or highly concentrated QIAGEN Internal Control can be added during nucleic acid extraction to provide both an extraction and an amplification control.

High linearity and precision of singleplex and duplex detection.
High linearity and precision of singleplex and duplex detection.
A 6-log range of both Norovirus RNA singleplex detection and Norovirus/IC duplex detection shows high precision and linearity. Error bars each represent ±1 SD of 3 real-time RT-PCR replicates.
Reliable dilution and storage of RNA standards using QuantiTect Nucleic Acid Dilution Buffer.
Reliable dilution and storage of RNA standards.
Serial tenfold dilutions of RNA standards (in vitro transcribed RNA) were prepared using either QuantiTect Nucleic Acid Dilution Buffer or RNase-free water, as indicated. These dilutions were used as template in one-step RT-PCR either directly (0 test) or after storage for 2 or 4 weeks at -20°C. Using QuantiTect Nucleic Acid Dilution Buffer resulted in lower CT values and improved stability of the standards.
