Immunofluorescence analysis of MEK1 was done on 70% confluent log phase MCF7 cells. The cells were fixed with 4% paraformaldehyde for 15 minutes; permeabilized with 0.25% Triton™ X-100 for 10 minutes followed by blocking with 5% BSA for 1 hour at room temperature. The cells were incubated with ABfinity™ MEK1 Recombinant Rabbit Oligoclonal Antibody (710446) at 2 µg-4 µg in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Flour® 488 Goat Anti-Rabbit IgG Secondary Antibody (A11008) at a dilution of 1:400 for 30 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® 594 Phalloidin (A12381). Panel d is a merged image showing cytoplasmic localization of MEK1. Panel e shows no primary antibody control. The images were captured at 20X 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.
MAP2K1 is a dual specificity mitogen-activated protein kinase (MAPK) kinase. It is an essential component of the MAP kinase pathway and stimulates the enzymatic activity of MAP kinases in response to various signals. Growth factors, cytokines, and proto-oncogenes transduce their signals through the activation of RAS, which leads to activation of the serine/threonine kinase RAF, and then to activation of MAPK kinase. MAP2K1 is activated by the Raf family member p74raf-1, through phosphorylation of serine residues at positions 217 and 221 in the activation loop.
