WebPolyethylene glycol (PEG) has been shown to potentiate antigen-antibody reactions. Study design and methods: A total of 500 patient samples were tested in parallel with reagent antibody-detection cells using blind-coded PEG and LISS potentiators. Results: 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.

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.
