Product Details

The FastLane Cell cDNA Kit provides a fast and simple procedure for preparing first-strand cDNA directly from cultured cells without RNA purification. The kit is supplied with wash and lysis buffers for preparing lysates and stabilizing RNA, gDNA Wipeout Buffer for eliminating genomic DNA contamination, and all reaction components for fast and efficient cDNA synthesis. The FastLane Cell cDNA Kit is ideal for experiments requiring rapid, high-throughput gene expression analysis.

Performance

cDNA synthesized by the FastLane Cell cDNA Kit enables highly sensitive and reproducible results in real-time two-step RT-PCR (see figures " Superior sensitivity in cancer research" and " Highly reproducible cDNA preparation"). The high quality of the cDNA also allows detection over a wide linear range from >105 cells down to one cell.
See figures

Principle

The FastLane Cell cDNA Kit uses FastLane technology to prepare cDNA directly from cultured cells in just 45 minutes. To ensure only RNA is detected in real-time RT-PCR, novel gDNA Wipeout Buffer is used to eliminate genomic DNA (see figure " Effective elimination of genomic DNA contamination"). Time and effort are saved as there is no need to design RNA-specific primers or probes.

When the FastLane Cell cDNA Kit is used together with optimized QuantiTect, QuantiFast, or Rotor-Gene Kits for real-time RT-PCR, several cell samples can be easily processed and analyzed within a few hours. This allows a snapshot of several transcripts in experiments such as validation of siRNA-mediated gene knockdown (see figure " Successful analysis of CDC2 knockdown").

The FastLane Cell cDNA Kit is part of the comprehensive range of FastLane Kits, which speed up and streamline the gene expression analysis workflow.

See figures

Procedure

With the FastLane Cell cDNA Kit, cDNA is obtained from cultured cells in just 45 minutes in a 4-step procedure: cell wash; cell lysis with integrated RNA stabilization; genomic DNA elimination; and cDNA synthesis. The synthesized cDNA is ready to use in real-time two-step RT-PCR.

The kit contains sufficient reagents for preparing cDNA from two 24-well cell-culture plates or one 48-well cell-culture plate. If working with a 96-well cell-culture plate, an additional QuantiTect Reverse Transcription Kit (50) needs to be purchased.

cDNA prepared with the FastLane Cell cDNA Kit can be analyzed by real-time two-step RT-PCR using one of the following QuantiTect Kits:

  • SYBR® Green detection: QuantiTect SYBR® Green PCR Kit
  • Probe detection: QuantiTect Probe PCR Kit
  • Multiplex probe detection: QuantiTect Multiplex PCR Kits

Alternatively, fast real-time two-step RT-PCR can be carried out when the FastLane Cell cDNA Kit is used in combination with a QuantiFast Kit:

  • SYBR® Green detection: QuantiFast SYBR® Green PCR Kit
  • Probe detection: QuantiFast Probe PCR Kits
  • Multiplex probe detection: QuantiFast Multiplex PCR Kits

Ultrafast real-time two-step RT-PCR can be achieved when cDNA prepared with the FastLane Cell cDNA Kit is analyzed on the Rotor-Gene Q cycler using one of the following dedicated Rotor-Gene Kits:

  • SYBR® Green detection: Rotor-Gene SYBR® Green PCR Kit
  • Probe detection: Rotor-Gene Probe PCR Kit
  • Multiplex probe detection: Rotor-Gene Multiplex PCR Kit 

QuantiTect and QuantiFast Kits are compatible with various real-time cyclers, including instruments from Applied Biosystems.

Applications

The FastLane Cell cDNA Kit is suitable for experiments which require a snapshot of individual transcript levels, such as:

  • Validation of siRNA-mediated gene knockdown
  • Evaluation of drug effects
  • Detection of gene regulation

FAQ

Is there a stopping point in the protocol for Suspended Cells using the FastLane Cell cDNA Kit?

Yes. Cells can be frozen after the wash step with Buffer FCW in Appendix D Protocol 'Processing Suspended Cells' of the FastLane Cell cDNA Handbook. Buffer FCW should be aspirated promptly after pelleting the cells during the wash step. Following the removal of Buffer FCW at step D5, the cells can be frozen. For future processing, thaw the cell pellet, and continue with the lysis step D6 using Buffer FCP.

FAQ ID -837
Can the FastLane Cell cDNA Kit also be used for qualitative end-point PCR?
Unfortunately, the FastLane Cell cDNA Kit cannot be used for classic end-point PCR. It is optimized for quantitative two-step RT-PCR, and can only be used for this application.
FAQ ID -834
Is it possible to use frozen cell pellets with the FastLane Cell cDNA Kit?

Yes, it is possible to process frozen cell pellets with the FastLane Cell cDNA Kit. Follow Appendix D protocol 'Processing Suspended Cells' in the FastLane Cell cDNA Handbook, starting from step D3. In our R&D labs, we let the pellet stand for 30 seconds at room temperature, add wash buffer FCW, spin down the cells promptly, and aspirate the wash buffer. In general, cells should not be vortexed or pipetted up and down during the wash step, and they should not be incubated in buffer FCW.

Note that it is essential to wash the cells with Buffer FCW at step D3. Omitting this step, or washing with PBS only, will inhibit subsequent steps in the protocol.

 

FAQ ID -835
Can I use my gene-specific primers with the FastLane Cell cDNA Kit and the QuantiTect Reverse Transcription Kit?

Yes, you can substitute the RT Primer Mix supplied in the FastLane Cell cDNA Kit and the QuantiTect Reverse Transcription Kit with your gene-specific primers. We suggest optimizinig the primer concentration by titration, starting at 1 uM, and gradually decreasing it to 0.5 uM final concentration in the reaction. Optimal amounts will depend on the specific primers you are using.

FAQ ID -812
How do the FastLane Cell cDNA Kit and QuantiTect Reverse Transcription Kit eliminate genomic DNA contamination?
The FastLane Cell cDNA Kit and QuantiTect Reverse Transcription Kit contain a unique buffer, called gDNA Wipeout Buffer, which ensures complete removal of gDNA after a brief incubation step.
FAQ ID -783
How many cells can be used with the FastLane Cell cDNA Kit?

A range of 1 x 104 - 1 x 105 cells can be used with the FastLane Cell cDNA Kit, depending on the culture plate format. Different plate formats require different amounts of buffers FCW and FCP. Refer to Appendix C, Table 4 in the FastLane Cell cDNA Handbook for the number of cells to seed per well and the buffer volumes to use. Note that the table is a starting point for optimization providing suggestions for cell numbers and buffer volumes. The number of cells to seed per well depends on factors such as cell type and culture conditions. For optimal results in real-time RT-PCR, it may be necessary to optimize the number of cells and buffer volumes.
