Immunofluorescence analysis of Phospho-IR pTyr1158 was performed using 70% confluent log phase HeLa cells treated with 10 nM Insulin for 10 minutes. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with ABfinity™ Phospho-IR pTyr1158 Rabbit Oligoclonal Antibody (710101) at 2 ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows untreated cells with no signal. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

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 receptor (IR), belongs to the growth factor receptor tyrosine kinase superfamily which regulates multiple signaling pathways. It is a heterotetrameric membrane glycoprotein consisting of alpha and beta subunits encoded by the INSR gene in humans. IR and IGF-1 receptors share major structural and functional similarity. The earliest cellular response to insulin stimulation is autophosphorylation of tyrosine in IR. In humans, the IR gene is located on chromosome 19.
