QIAquick® Spin Columns can now be used on any vacuum manifold with luer connectors, for example, the QIAvac 6S or QIAvac 24 with QIAvac Luer Adapters. This protocol is designed for removal of primers <10 bases, enzymes, salts, and unincorporated nucleotides from biotin-, or DIG-labeled DNA fragments and oligonucleotides >17 nucleotides.
Supplementary protocol using the EZ1 Advanced or EZ1 Advanced XL with the EZ1 DNA Investigator Kit
The following protocol is optimized for transient transfection of 293 cells in 96-well plates without pre-plating of cells 24 h prior to transfection. Cell plating and transfection are performed on the same day, making this protocol rapid and convenient.
The following protocol is optimized for transient transfection of CHO cells in 96-well plates without pre-plating of cells 24 h prior to transfection. Cell plating and transfection are performed on the same day, making this protocol rapid and convenient.
The following protocol is optimized for transient transfection of COS-7 cells in 96-well plates without pre-plating of cells 24 h prior to transfection. Cell plating and transfection are performed on the same day, making this protocol rapid and convenient.
The following procedure is for co-transfection of adherent cells using siRNA and plasmid DNA in one well of a 24-well plate. This procedure is provided as a starting point for optimization of siRNA and plasmid DNA co-transfection in mammalian cells using TransMessenger™ Transfection Reagent.
For parallel preparation of genomic, bacterial, or viral DNA or viral RNA from more than 24 samples, we recommend using QIAamp® Spin Columns with 4-6 ml collection tubes. Any tube with an inner diameter of 9-10 mm (outer diameter 11-12 mm) is suitable.
This protocol is for purification of up to 100 µg endotoxin-free plasmid DNA using QIAGEN-tip 100.
This protocol is designed for the rapid, easy, and non-toxic preparation of up to 2 mg genomic DNA from not more than 2 g of tissue using QIAGEN-tip 2500. QIAGEN® Genomic-tips 20/G, 100/G, and 500/G can also be used with this protocol by reducing the amount of starting material according to the table on page 2. The purified genomic DNA ranges in size from 50-150 kb.
This protocol is designed to provide up to 150 μg BAC/PAC/P1 DNA or up to 400 μg cosmid DNA.
This protocol is designed for 96 parallel plasmid DNA preparations from 1.3 ml overnight cultures.
This protocol is designed for isolation of up to 200 μg RNA from 150 mg plant tissue or up to 1 mg RNA from 600 mg plant tissue and is for use with QIAGEN-tip 100 or QIAGEN-tip 500, respectively.
The following protocols have been designed for the use of Ni-NTA Superflow Columns on the QIAvac 6S vacuum manifold or in gravity-flow applications on the QIArack. Up to 15 mg 6xHistagged protein can be purified per column from cleared lysate derived from up to 1 liter of (E. coli) bacterial culture.
The two protocols given below are for the use of the Ni-NTA Superflow 96 BioRobot® Kit in manual procedures. The kit has been specially designed and optimized for automated 6xHis-tagged protein purification on QIAGEN® BioRobot Systems. For more details of the advantages of BioRobot Systems see the Ni-NTA Superflow 96 BioRobot Kit Handbook supplied with the kit or contact one of the QIAGEN Technical Service Departments or local distributors listed on the last page of the handbook.
