MW: 50,000
Extinction Coefficient: 1.35

Frozen in 20 mM phosphate, pH 7.4, with 150 mM NaCl and 0.05% NaN3.

Isolated fab fragments can be used to bind antigen to antibody in solution or on the cell surface without causing the undesired complications of cross-linking and precipitation, or "patching" and capping," respectively.

Storage: <= -20°C

Purity: >=95% by SDS-PAGE. No reaction by IEP to antisera to human IgG-fc.

Prepared from plasma shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.
