Immunopurification of gonadotrophin surge-attenuating factor (GnSAF) bioactivity

Sorsa-Leslie T , Harris W , Mason H , Fowler P

Objective We aimed to immunopurify GnSAF, using antibodies with demonstrated GnSAF bioactivity-blocking/binding activity, in order to confirm 2 new candidate amino acid sequences for human ovarian GnSAF (Fowler et al. Mol Human Reprod 2002;8:823-832).Methods Rat antiserum, raised against a 60-70 kDa band of partially purified GnSAF, was immobilised on anti-rat IgG Dynabeads. In addition, a human antibody, derived from a phage display antibody library a...

Engineering of single chain antibodies selected from a phage display library into human IgGs that recognise gonadotrophin surge-attenuating factor (GnSAF) bioactivity

Sorsa-Leslie T , Harris W , Mason H , Fowler P

Introduction. We have previously used a synthetic phage display library to derive single chain (ScAbs) antibodies which bind GnSAF bioactivity in-vitro. However, recovery of GnSAF using the ScAbs, which tended to aggregate and become unstable, was limited. We have therefore engineered these ScAbs into full-length human IgG forms.Methods. CDR regions from soluble expression plasmids for two different GnSAF-recognising ScAbs were amplified by PCR. Two uni...
