Anti-Mouse CD8 beta In Vivo Antibody – Low Endotoxin (53-5.8) [ICH1046]
$375.00 – $2,950.00
Bulk anti-CD8 beta In Vivo Antibody – Low Endotoxin (53-5.8)
ICH1046 is up to 30% cheaper for academia & non-profits and up to 55% cheaper for industry than the equivalent products BE0223 (low endotoxin) from Bio X Cell.
ichorbio’s anti-CD8 beta In Vivo Antibody – Low Endotoxin (53-5.8) is manufactured in a cGMP compliant, ISO Quality Standard 9001:2015 facility. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio: the best antibodies for in vivo research.

Mouse
Anti-CD8 beta In Vivo Antibody – Low Endotoxin (53-5.8) recognizes an epitope on mouse CD8b.2 and antibody clone 53-5.8 is specific for Ly-3.2 and has low reactivity with Ly-3.1
This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
Majority of thymocytes, cytotoxic T cell subsets
CD8b is also known as Lyt-3.2 or Ly-3.2. It is a member of the Ig superfamily expressed as a heterodimer with the CD8A chain on a subset of MHC class I-restricted T cells and most thymocytes.
