Product Description

NOTE: R942-25 was previously sold under product #46-0286. When re-ordering, please use #R942-25. This antibody is designed to specifically detect recombinant proteins containing the seven amino acid 6xHis-Gly epitope. This epitope is present in many expression vectors encoding an N-terminal 6xHis tag. The HisG antibody recognizes the following sequence: -His-His-His-His-His-His-Gly. This product contains enough material for 25 Western blots. Western blot experiments with 100 ng of recombinant Positope™ control protein gave a detectable signal within 15 minutes using a chromogenic substrate. The Positope™ control protein is a 53 kDa recombinant protein that contains seven epitope tags, including His(C-term), HisG, c-myc, and V5. For Western blot, we recommend diluting the AP-conjugated antibody 1:2000 into Tris-Buffered Saline (TBS) containing 0.1% (v/v) Tween-20 and 1% (w/v) nonfat dry milk. Epitope tags provide a method to localize gene products in a variety of cell types, study the topology of proteins and protein complexes, identify associated proteins, and characterize newly identified, low abundance or poorly immunogenic proteins when protein specific antibodies are not available.
