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.
ichorbio’s 53-5.8 in vivo antibody is available in the following bulk sizes:
1mg, 5mg, 25mg, 50mg and 100mg
ichorbio regularly manufactures multi-gram amounts of our anti-CD8 beta 53-5.8 clone – please contact us for pricing.

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.

Sample: Frozen sections of tumor tissues from tumor bearing C57BL / 6 mice (inoculated with LLC cells)
1. Tumors were dissected, fixed in 4% paraformaldehyde, and dehydrated in 30% sucrose;
2. Frozen tumor sections were prepared at 25 ℃ and rinsed in PBS;
3. Blocking buffer: PBS containing 0.3% Triton + 5% goat serum; Sections were blocked for 1h;
4. Primary antibodies: Diluted in blocking buffer; incubated overnight at 4℃. Final concentration of ichorbio CD8 beta antibody clone 53-5.8 (low) 3.5μg/ml, Final concentration (high) 35μg/ml. Positive signals were detected at both high and low concentrations
5. Washed by PBST; Secondary antibodies: incubated at 4℃ for 6h; DAPI: 2h
Details of secondary antibody:
Alexa Fluor 647-AffiniPure Goat Anti-Rat IgG (H+L) (min X Hu,Bov,Hrs Sr Prot) antibody – Jackson Immunoresearch Labs Cat# 112-605-062 – Conc. 7.5μg/ml.
