Immunofluorescence analysis of ERK1 was done on 70% confluent log phase U2OS 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™ ERK1 Recombinant Rabbit Monoclonal Antibody (701183) 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 ERK1. Panel e shows no primary antibody. 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™ 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.
ERK-1 is a classical MAP kinase involved in intracellular signaling in response to extracellular stimulus. ERK-1 is activated by growth factors, hormones, and phorbol esters. ERKs are widely expressed in different cells, and are involved in control of cell proliferation, cell differentiation, and cytoskeletal regulation. ERK-1 is a serine/threonine kinase which phosphorylates cytoplasmic signaling molecules, cell surface receptors, transcription factors, and microtubule associated proteins upon activation by molecules upstream in the signal transduction pathway.
