Report
活性（Bioactivity）-ELISA
Immobilized Monoclonal Anti-DM-1&DM-4 Antibody, Mouse IgG1 (Cat. No. DM1-Y73) at 2 μg/mL, add increasing concentrations of Trastuzumab-DM1 (T-DM1), and then add Biotinylated Human Her2, His,Avitag, premium grade (Cat. No. HE2-H82E2) at 8 μg/mL. Detection was performed using HRP-conjugated streptavidin with sensitivity of 0.5 ng/mL (QC tested).
Protocol
Immobilized ADC-DM4 at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-DM-1&DM-4 Antibody, Mouse IgG1 (Cat. No. DM1-Y73) with a linear range of 0.20-6.25ng/mL (Routinely tested).
Protocol
Immobilized Monoclonal Anti-DM-1&DM-4 Antibody, Mouse IgG1 (Cat. No. DM1-Y73) at 5 μg/mL, add Trastuzumab-DM1 in the 50% Human serum and then add Biotinylated Human Her2, His,Avitag, premium grade (Cat. No. HE2-H82E2) at 0.5 μg/mL. Detection was performed using HRP-conjugated Streptavidin (Acro, Cat. No. STN-NH913) (Routinely tested).
Protocol
Serial dilutions of DM1 were added into Monoclonal Anti-DM-1&DM-4 Antibody, Mouse IgG1 (Cat. No. DM1-Y73): Trastuzumab-DM1 binding reactions. The half maximal inhibitory concentration (IC50) is 0.148 μg/mL (Routinely tested).

背景
Mertansine (DM-1) is a tubulin inhibitor that binds to the ends of microtubules and inhibits microtubule dynamics. DM-1(Mertansine) has antitumor activity and functions as a regulator of tubulin. It is an alpha-amino acid ester, a carbamate, an epoxide, an organic heterocyclic tetracyclic compound, an organochlorine compound, a mercaptan, and a maydenin alkaloid. DM-1, derived from Mydenin, is a cytotoxic component of antibody-drug conjugations that produce antibody-drug conjugations via a sulfhydryl group splice with SPP (n-succinimide 4- (2-pyridyl dithio)) or SMCC (4- (3-mercapto-2, 5-dioxy-1 pyrrolidyl) -cyclohexanic acid) splice.
