Western blot analysis of Phospho-IGF1R pTyr1135/1136 in whole cell extracts of HeLa cells treated with Insulin (100ng/ml, 15 min) using a Phospho-IGF1R pTyr1135/1136 recombinant rabbit monoclonal antibody (Product # 701067) at a dilution of 2.5ug/ml. To confirm specificity, competition was performed by preincubation with the phosphopeptide to inhibit antibody binding (lane 1). Results show a band at ~90kDa.

ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
Insulin growth factor 1 receptor belongs to the family of tyrosine receptor kinases. It is involved in activation of various substrates including IGF and neurotensin, regulation of metabolism, cell division, maintenance, and inflammation response. The protein is a tetramer consisting of two alpha, and two beta subunits. The alpha-subunits binds to insulin growth factor 1 with higher affinity than to insulin growth factor 2. Binding results in a conformational change, followed by autophosphorylation of IGF-1R at positions 1134, 1135, 1136. The activated IGF-1R in turn, causes phosphorylation of substrate proteins, followed by sequential activation of RAS, RAF, and mitogen-activated protein kinase isoforms ERK, p38, and JNK, leading to the transcription of genes that drive proliferation. This antibody recognizes the beta-subunit of IGF1R.
