Background Information
MTAP is a 5-deoxy-5-methylthioadenosine (MTA) phosphorylase, converting MTA to salvageable intermediates including adenine and 5-methylthioribose-1-phosphate. MTAP is abundant in normal cells, but it is frequently found to be deleted in a variety of cancers. Its deficiency is common in cancer cell lines as well as in primary leukemia, lung cancer, melanoma, bladder cancer, gliomas and breast cancer.

Reviews
What customers say
Both reviewers gave this antibody a perfect 5-star rating for Western Blot. One user confirmed it successfully marked a knockout sample in HEK 293 cells at a 1:1000 dilution. The other observed a band at the expected size with clean background and strong signal in mouse liver lysate at 1:2000 dilution. Overall, users report reliable specificity, strong signal, and clean results across different sample types and dilutions.
