H2Mab-139
H2Mab-139 (H2Mab-141;H2Mab-19) is an anti-HER2 monoclonal antibody. H2Mab-139 specifically binds to HER2 on various cancer cells. H2Mab-139 can detect HER2 overexpression in colorectal cancer via flow cytometry and immunohistochemical analysis. H2Mab-139 exhibits anti-tumor activity in mouse oral cancer and breast cancer xenografts. H2Mab-139 is applicable to research related to multiple cancers including colon cancer, oral cancer, and breast cancer.

Human
H2Mab-139 (10 μg/mL; 30 min at 4°C) specifically binds to HER2 on LN229/HER2 glioblastoma cells and the colorectal cancer cell lines Caco-2, HCT-116, HCT-15, HT-29, LS 174T, COLO 201, COLO 205, HCT-8, SW1116, and DLD-1 in flow cytometry assays[1].
H2Mab-139 (10 μg/mL) specifically detects HER2 protein with a molecular weight of approximately 200 kDa in LN229/HER2 glioblastoma cell lysates via Western blotting[1].
H2Mab-139 (10 μg/mL; 1 h at room temperature) specifically stains the cell membrane of HER2-positive human colon cancer tissue sections in immunohistochemical assays[1].
H2Mab-19 (6 ng/mL to 100 μg/mL) maintains high binding affinity for HER2 in HER2-expressing BT-474, HSC-2, and SAS cell lines, with Kd values of 2.3 × 10-8 M, 9.5 × 10-9 M, and 5.5 × 10-9 M, respectively[2].
H2Mab-19 (5 h at 37°C) exhibits high CDC activity against BT-474, HSC-2 and SAS cell lines, with cytotoxicity rates of 46%, 51% and 53%, respectively[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
H2Mab-19 (100 μg per dose; i.p.; on days 1, 6, and 14 after cell implantation) significantly reduces tumor development and tumor weight in HSC-2 oral cancer xenografts[2].
