WebOct 4, 2013 · Both ficin and papain work well for adsorptions. We have routinely used ficin in our reference lab for decades, both for antibody ID and adsorptions. And both enzymes can be used as constituents of ZZAP. A couple of years ago I compared cysteine-activated papain and ficin as constituents of ZZAP, and the volume of 1%ficin used in ZZAP. WebApr 2, 2024 · It should be noted that (1) the optimal PEG density for protein rejection depends mainly on the particle size and surface curvature; 126 (2) NPs also have weak resistance of protein adsorption at the low PEG coverage density, whereas PEG coating cannot wholly prevent protein adsorption at the high PEG coverage density; 78,127 (3) the … calvin klein uae online

WebPEG is a water soluble polymer that “eliminates” water allowing RBCs to get closer together. PEG is more effective than LISS or albumin in detecting weak antibodies. PEG is added after the immediate spin (IS) and incubated. There is no 37C interpretation when using PEG because centrifuging RBCs with added PEG can cause false positives. WebPEG.
