Anti-ADAM1B Antibody, Rat Monoclonal (#57)


SKU: 73-010 Research Area: Applications:



ADAM1B may play a role in spermatogenesis, sperm maturation and fertilization. Molecular mass is 89,369 with 806 amino acids. N-terminal signal peptide with 33 amino acids from this protein is processed to give propeptide, which may undergo further processing.

Fig.1 Immunofluorescent staining of ADAM1B in sperm by using anti-ADAM1B antibody. Fresh sperm collected from the epididymis of mice were fixed in 4% paraformaldehyde and then immunostained with the anti-ADAM1B antibody (#57) at 1/300 dilution.



Fig.2. Immunohistological staining of ADAM1B in mouse testis using anti-ADAM1B antibody (#57). A section of formalin fixed and paraffin embedded mouse testis was treated with the anti-ADAM1B antibody at 1/100 dilution after deparaffization and antigen retrieval. The 2nd antibody, anti-rat IgG conjugated with AF488 (Abcam) was used at 1/1,000 dilution. DNA was stained with DAPI and the merged image was shown (Merge). The bright field microsopic picture of the same region was shown on the right.
