Bulk anti-CD11b In Vivo Antibody – Low Endotoxin (M1/70)
ichorbio’s anti-CD11b In Vivo Antibody – Low Endotoxin (M1/70) 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 M1/70 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-CD11b M1/70 clone – please contact us for pricing.

Anti-CD11b In Vivo Antibody – Low Endotoxin (M1/70) recognizes the (Mr 170 kD) alpha m subunit of Mac-1 (CD11b/CD18, alpha m beta 2 integrin), the mouse macrophage-granulocyte specific antigen. Mac-1 is a macrophage differentiation antigen associated with type three complement receptor and mediates adhesion to CD54 (ICAM-1).
The Mac-1 CD11b antigen is present on macrophages, granulocytes, natural killer cells, blood monocytes. CD11b is expressed on 8% spleen cells, 44% bone marrow cells and less than 1% of 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 CD11b antibody clone M1/70 (low) 2μg/ml, Final concentration (high) 10μg/ml. Positive signals were detected at both high and low concentrations
5. Washed by PBST; Secondary antibodies: incubated at 4℃ for 6h; DAPI: 2h
