Commercial kits for applications in molecular biology:


HisExpress protein purification columns: http://www.claremontbio.com/HisExpress_Protein_Purification_Columns_s/72.htm (available at http://www.bioquote.com/product.php?id=291680)

PrepEase his-purification: http://www.affymetrix.com/estore/browse/brand/usb/product.jsp?navMode=34000&productId=131366&navAction=jump&aId=productsNav#1_1

Affinity chromatography products at Jena Bioscience: http://www.jenabioscience.com/cms/en/1/browse/1450_affinity_chromatography.html?gclid=CJCPmK6HvrUCFQtY3godFWEAtg


Kit Use Advantages Disadvantages Time Experience
Promega Wizard SV miniprep DNA isolation Quick Low yield 45 - 60 min
Promega PureYield™ Plasmid Miniprep System High-purity DNA isolation
Machery-Nagel NucleoBond Xtra Midi (midiprep) DNA isolation High yield (~20 ug), pure product. Slow 2 d Yields of 100-140 ng/uL in 200 uL, for a total of about 20 ug. Yield may depend on skill in handling washing and resuspension of DNA pellet. Might be more efficient to do several (~10) parallel minipreps instead?
Qiaquick gel extraction DNA extraction from gel Fast Impure product Impurities give absorbption peak at 230 nm in eluted product.
Qiaquick PCR purification Purification of PCR products Fast 15 min
QIAEX II gel extraction DNA extraction from gel Higher purity than qiaquick Slower than Quiaquick 1-5 h Yield of about 200 ng from ~1.5 ug starting amount of plasmid.
QIAGEN PCR Cloningplus Kit Subcloning (TA cloning) ? ?  ?
Dongsheng Bio Eco-friendly Plasmid miniprep kit DNA isolation  ? -
Dongsheng Bio PCR and DNA Fragment Purification Kit Purification of PCR fragments  ?
QiaAmp
