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.
PDI (ER marker) also known as protein disulfide isomerase is an enzyme present in the ER which plays a very important role in protein folding, by facilitating formation of correct disulphide bonds. Processing and maturation of the secretory proteins in the endoplasmic reticulum are actively done by the family of PDI proteins. This class of proteins show similar homology to the cytoplasmic protein thioredoxin. The protein catalyses the thiol/disulphide interchange interactions. Also depending upon the type of polypeptide substrate and redox potential, the protein brings about protein disulfide formation, isomerization or reduction.
