ActionsMolecular Biology Reagents/Chemicals
MIDSCI™ gives you ultra-pure, cost-competitive molecular biology reagents and lab chemicals for life science research; often with significant cost savings over Sigma Aldrich and other lab reagent providers.
PR1MA™ Chemicals can help with a wide variety of research-based requirements.
Use our glycerol for polyacrylamide gel electrophoresis. Eliminate Agrobacterium after inoculation with the carbenicillin we carry. Or detect β-Galactosidase activity with X-GAL which, when combined with the IPTG we stock, can be used to detect lac gene expression in cloning applications.
We also carry Luria Broth (Lennox), for the propagation and maintenance of E. coli; DTT, in order to maintain –SH groups in a reduced state; and high gel strength agar for tissue culture and microbiological work.

Electrophoresis Buffers
QuickSilver - TAE (Tris-acetate-EDTA)
TAE is ideal for separation of large DNA fragments in agarose gels and is used as running buffer and in gel preparation.
TAE is the buffer of choice when recovering DNA from gels and when downstream processing involves enzymatic reactions. Final concentration of a 1X working solution is 40mM Tris, 20mM acetic acid, 1mM EDTA.
QS1000 QuickSilver TAE Buffer, 1X, 100 packs
QuickSilver - TBE (Tris-borate-EDTA)
TBE is used in gel preparation and as a running buffer for electrophoresis of nucleic acids. TBE works best for resolution of smaller fragments (<2kb). Its higher buffering capacity makes it useful for longer runs. The final concentration of a 1X working solution is 89mM Tris, 89mM boric acid, 2mM EDTA.
QS1001 QuickSilver TBE Buffer, 1X, 50 packs
QuickSilver - Fast Running Buffer
QuickSilver Fast Running Buffer is a proprietary blend formulated for agarose gel electrophoresis at high voltage (300-350V). Its strong buffering capacity minimizes heat generation all allows for extremely fast separation of fragments smaller than 5kb. A typical 30-minute run can be performed in just 10 minutes using this buffer.
QS1002 QuickSilver Fast Running Buffer, 1X, 100 packs
Protein Electrophoresis Buffers
QuickSilver™ TGS (Tris-Glycine-SDS)
Tris-Glycine-SDS is one of the most common running buffers used for SDS-PAGE. A 1X solution contains 25mM Tris, 192mM Glycine and 0.1% SDS.
QS1100 QuickSilver Tris Glycine-SDS Buffer, 1X, 50 packs
QuickSilver™ Tris-MES-SDS
Small to medium molecular weight proteins can be resolved on SDS-PAGE gels using Tris-MES-SDS as a running buffer. Proteins resolve faster in gels using Tris-MES-SDS as a running buffer than those using Tris-MOPS-SDS. A 1X solution has a final concentration of 50mM Tris, 50mM MES, 0.1% SDS and 1mM EDTA.
QS1101 QuickSilver Tris-MES-SDS Buffer, 1X, 50 packs
QuickSilver™ Tris-MOPS-SDS
Tris-MOPS-SDS is ideal for use as a running buffer when resolving medium to large proteins with SDS-PAGE. Gels run with Tris-MOPS-SDS buffer run slower than those using Tris-MES-SDS buffer. The final concentration of a 1X working solution is 50mM Tris, 50mM MOPS, 0.1% SDS and 1mM EDTA.
QS1102 QuickSilver Tris-MOPS-SDS, 1X, 50 packs
Western Blotting, ELISA, Cell Culture, Chromatography
QuickSilver™ PBS and PBST
Because its osmolality and ion concentration closely mimic that of the human body, PBS is commonly used for cell culture applications, as well as HPLC and MS. PBST is a wash buffer and diluent for ELISA. The 1X PBS solution contains 137mN NaCl, 2.7mM KCl and 10mM phosphate. PBST is supplemented with 0.05% Tween-20.
