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.
Recombinant rabbit polyclonal antibodies are unique offerings from Thermo Fisher Scientific. They are comprised of a selection of multiple different recombinant monoclonal antibodies, providing the best of both worlds – the sensitivity of polyclonal antibodies with the specificity of monoclonal antibodies - 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 – a recombinant rabbit polyclonal antibody has a known mixture of light and heavy chains. The exact population can be produced in every lot, circumventing the biological variability typically associated with polyclonal antibody production.
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.
