Sigma Aldrich Fine Chemicals Biosciences TWEEN 20, 9005-64-5, MFCD00165986, 500mL
Tween 20 is a polyoxyethylene sorbitol ester that belongs to the polysorbate family. It is a nonionic detergent having a molecular weight of 1,225 daltons, assuming 20 ethylene oxide units, 1 sorbitol, and 1 lauric acid as the primary fatty acid. The ethylene oxide subunits are responsible for the hydrophilic nature of the surfactant, while the hydrocarbon chains provide the hydrophobic environment. Sorbitol forms the backbone ring to which the ethylene oxide polymers are attached.

AG Scientific Inc CHAPS, High Purity, 10 G
CHAPS is a zwitterionic detergent that is widely used in the protein purification process. As part of this class of detergents, CHAPS contains both a positive and a negative group, but does not have a net overall charge. CHAPS has a relatively low biomembrane affinity, but is effective in inducing hemolysis and protein solubilization within specific concentration ranges. CHAPS is classified as a non-denaturing surfactant with a critical micelle concentration of 6-10mM.ApplicationsIn the laboratory, CHAPS and other zwitterionic detergents can be used for inducing cell lysis prior to protein isolation.CAS Number: 75621-03-03Molecular Weight: 614.9Chemical Formula: C32H58N2O7SSolubility: Soluble in DMSO or DMFStorage Temperature: Room TemperatureResearch or further manufacturing use only, not for food or drug use.

Waters Corp RapiGest SF, 1 mg , 5/pk
RapiGest SF, is a patented anionic surfactant that drastically improves in-solution protein digestion in terms of speed and peptide recovery. It is especially valuable in protein sample preparation for mass spectrometry (MS) analysis by avoiding high background noise often seen from other common surfactants. RapiGest SF is available in a variety of formats. This part contains five, 1mg vials that contain enough material for 1-50 digestions. Add RapiGest SF to your proteolytic digestion, (using trypsin or other enzymes) to enhance digestion speed and increase peptide recovery. US Patent No: 8,580,533
