Description
The MJ7/18 monoclonal antibody specifically binds to mouse CD105 (also known as endoglin) which is a homodimer of 90-kDa subunits and is predominantly expressed on vascular endothelial cells. High levels of mouse endoglin mRNA have been reported to be detectable in the ovary, uterus, NCTC-2071 fibroblasts, and to a lesser extent, in heart, muscle and stromal cells in connective tissue of various organs. Endoglin has been reported to play an essential role in embryonic angiogenesis. Both mouse and human endoglin display strong amino-acid sequence homology to the transmembrane and cytoplasmic regions of the type III TGF-ß receptor.
Immunohistochemistry: Clone MJ7/18 was tested in development for immunohistochemical staining of acetone-fixed frozen sections. IHC of formalin-fixed paraffin embedded sections is not recommended. This antibody has been reported to predominantly stain vascular endothelial cells. The isotype control recommended for use with this antibody is Purified Rat IgG2a κ Isotype Control (Cat. No. 559073). For optimal indirect immunohistochemical staining, the MJ7/18 antibody should be titrated (1:10 to 1:50 dilution) and visualized via a three-step staining procedure in combination with Biotin Goat Anti-Rat Ig (Cat. No. 559286) as the secondary antibody and streptravidin-HRP (Cat. No. 550946) together with the DAB detection system (Cat. No. 550880).
Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. An isotype control should be used at the same concentration as the antibody of interest.
3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
5. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
