DDDDK-Tag(binds to flag sequnence) rabbit pAb
抗體,也叫免疫球蛋白(Ig),是一種能特異性結(jié)合抗原的糖蛋白,而抗原是在易感染動物體內(nèi)引發(fā)抗體產(chǎn)生的物質(zhì)。在體內(nèi),抗體是由于外源性分子的侵襲而產(chǎn)生的??贵w以一個或者多個Y字形單體存在,每個Y字形單體由4條多肽鏈組成,包含兩條相同的重鏈和兩條相同的輕鏈。輕鏈和重鏈?zhǔn)歉鶕?jù)它們的分子量大小來命名的。Y字形結(jié)構(gòu)的頂端是可變區(qū),為抗原結(jié)合部位。任何一個抗體的輕鏈都可以分為κ或λ型(基于小分子多肽結(jié)構(gòu)上的差異),每一個抗體的重鏈則決定了它的類或型。

背景
The DYKDDDDK (FLAG) peptide has been used extensively as a general tag in expression vectors. This peptide can be expressed and detected with the protein of interest as an amino-terminal or carboxy-terminal fusion. N-terminal FLAG vectors provide an Ek cleavage site for removal of the fusion tag. The FLAG peptide is likely to be located on the surface of a fusion protein because of its hydrophilic nature. As a result, the FLAG peptide is more likely to be accessible to antibodies. A FLAG-tag can be used in many different assays that require recognition by an antibody, such as western blotting, immunocytochemistry, immunoprecipitation, flow cytometry, protein purification, and in the study of protein-protein interactions, cell ultrastructure, and protein localization and so on.
