Bsa digestion by trypsin
WebI guess since BSA MW is ~ 66kDa your gel concentration is appropriate since you have a problem with the 15% gel as the products are too small and too abundant to resolve. I disagree on the gel percentage. I did run a lot of gels wit proteins in the 50-70 kDa range and I used 7 or 8% gels for that. WebBovine serum albumin (BSA) that was acidified and hydrolysed with pepsin, showed the highest extent and most efficient hydrolysis by trypsin. BSA in the chyme that would be first emptied from the stomach, virtually bypassing gastric acidity and peptic action, reduced trypsin-catalysed hydrolysis by up to 58% compared to the acidified, intact ...

WebFeb 15, 2012 · The sensing mechanism is based on trypsin digestion of the protein template of BSA-stabilized Au nanoclusters. The decrease in fluorescence intensity of BSA-Au nanoclusters caused by trypsin allows the sensitive detection of trypsin in the range of 0.01–100 μg/mL. WebFor digestion of native proteins, dissolve the protein in 50mM NH 4 HCO 3 (pH 7.8) or 50mM Tris-HCl (pH 8) without urea. Add Trypsin Gold, Mass Spectrometry Grade, to a final protease:protein ratio of 1:100 to 1:20 (w/w). Incubate overnight at 37°C.
