Grade: recombinant human


Source: Glycosylated recombinant ecto-domain of gp 41 (amino acids 546-682, HxB2) produced in pichia pastoris(without the membrane spanning and cytoplasmic domains). The protein is heterogeneously glycosylated and is seen predominantly as a series of bands from 20,000 to 30,000 daltons on Western blot.

Reactivity: Reacts with Aids sera and human monoclonals specific for conformational and linear epitopes as determined by ELISA/Western blot. Polyhistidine is immunologically unreactive.

Form: 6M Urea, 0.5M NaCl, 0.02M sodium phosphate, 0.2 wt% Triton X-100 assay
