6x-His Tag Recombinant Polyclonal Antibody (21HCLC), Invitrogen™
Rabbit Recombinant Polyclonal Antibody
Supplier: Thermo Scientific 710286
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. Recombit rabbit polyclonal antibodies are unique offerings from Thermo Fisher Scientific. They are comprised of a selection of multiple different recombit 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 recombit 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 recombit 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.The 6x His tag is a synthetic oligo peptide consisting of 6 consecutive histidine residues (HHHHHH). The His tag is commonly expressed as a tag at either N-or C-terminal regions of recombit proteins to allow isolation or purification by immobilized metal affinity chromatography. Epitope tagging is a technique in which a known epitope is fused to a recombit protein using genetic engineering. By choosing a particular epitope and recombit protein combination, epitope tagging makes it possible to detect proteins for which no antibody is available. His epitope tagged proteins that contain a stretch of histidine residues at the carboxyl or amino terminus are used for purification of recombit proteins by means of metal chelate chromatography due to metal binding properties of histidine clusters on His tagged proteins. For example, the affinity of the histidine-tag motif to Ni2+ by chelation is strong and selective enough to enable purification of the protein to homogeneity by affinity chromatography on a Ni2+-NTA adsorbent. His tag-specific antibodies are used to facilitate detection or coimmunopreciptation of tagged proteins.
