抗体来源（Source）
Biotinylated Anti-His Tag Antibody(AY63), Fab is a Fab fragment of a mouse monoclonal antibody recombinantly expressed from human 293 cells (HEK293). The mouse monoclonal antibody is produced from a hybridoma resulting from fusion of SP2/0 myeloma and B-lymphocytes obtained from a mouse immunized with a poly-his tagged protein.
特异性（Specificity）
This product is a specific antibody specifically reacts with His tag protein，and can recognizes C-terminal, N-terminal, and internal His tagged fusion proteins.

电泳（SDS-PAGE）
Biotinylated Anti-His Tag Antibody(AY63), Fab on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
活性（Bioactivity）-ELISA
Immobilized SARS-CoV-2 Nucleocapsid protein, His Tag (BQ.1/Omicron) (Cat. No. NUN-C52Hx) at 1μg/mL (100μL/well) can bind Biotinylated Anti-His Tag Antibody(AY63), Fab (Cat. No. HIS-BVM539) with a linear range of 0.2-100ng/mL (QC tested).
Protocol
背景（Background）
His tag is a very small molecular weight tag, usually composed of 6-10 histidine (His). It is one of the commonly used tags for protein purification and detection. Due to its small molecular weight, fusion into the target protein has almost no effect on the structure and characteristics of the protein. Anti-his tag antibody can accurately detect, locate and purify His tag fusion protein, so as to provide convenience for the vast number of researchers.
