Biotin-protein ligase (EC 6.3.4.15) activates biotin to form biotinyl 5' adenylate and transfers the biotin to biotin-accepting proteins. It also functions as a biotin operon repressor. The protein is encoded by the birA gene. Other names for this enzyme include: biotin ligase; biotin operon repressor protein; birA; biotin holoenzyme synthetase; biotin-[acetyl-CoA carboxylase] synthetase.

CUTANA pAG-Tn5 is the key reagent for performing efficient mapping of chromatin features in Cleavage Under Targets and Tagmentation (CUT&Tag) [1]. CUT&Tag offers significant improvements in signal to noise at reduced cell inputs and sequencing depth compared to ChIP-seq. As a fusion of Proteins A and G to a highly active E. coli transposase mutant (Tn5), CUTANA pAG-Tn5 is compatible with target antibodies from a broad spectrum of host species. It also comes without an epitope tag, making it suitable for tag-mediated CUT&Tag (e.g. FLAG, HA, TY1, V5, etc.). This product is highly purified to remove contaminating E. coli DNA, which can be tagmented during storage and complicate analysis at low cell numbers. For superior normalization as well as antibody validation and reaction monitoring, SNAP-CUTANA™ nucleosome spike-ins (e.g. EpiCypher 19-1002) are recommended. The Tn5 comes charged with mosaic adapters and is ready to be used in CUT&Tag.
