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™ oligoclonal antibodies comprise a selection of multiple different recombinant monoclonal antibodies, providing the best of both worlds—the sensitivity of a polyclonal antibody with the specificity of a monoclonal, all delivered with the consistency only found in a recombinant antibody. While functionally the same as a polyclonal antibody—recognizing multiple epitope sites on the target and producing higher detection sensitivity for low abundance targets when compared with monoclonal antibodies—an oligoclonal antibody has a known mixture of light and heavy chains. This exact population can be produced in every lot, circumventing the biological variability typically associated with polyclonal antibody production.
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 IGF-1R.
