Performance Data
Bioactivity-ELISA
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) (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 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 (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).
Protocol
Cross Verification
ELISA binding of Monoclonal Anti-DM-1&DM-4 Antibody, Mouse IgG1 (Cat. No. DM1-Y73) with Trastuzumab Deruxtecan, Sacituzumab Govitecan, Disitamab Vedotin (RC48), Trastuzumab MMAE and Trastuzumab-DM1 conjugated antibody respectively.
The coating antibody was Monoclonal Anti-DM-1&DM-4 Antibody, Mouse IgG1 (Cat. No. DM1-Y73), used at 1 μg/mL concentration. The primary antibody were different payload conjugated antibodies, including Trastuzumab Deruxtecan, Sacituzumab Govitecan, Disitamab Vedotin (RC48), Trastuzumab MMAE and Trastuzumab-DM1 conjugated antibodies used at 0.5 μg/mL concentration. The secondary antibody was Peroxidase AffiniPure Goat Anti-Human IgG, Fcγ fragment specific (min X Bov, Hrs, Ms Sr Prot) (Jackson, Cat. No. 109-035-098) used at 1:12000 concentration.
Monoclonal Anti-DM-1&DM-4 Antibody, Mouse IgG1 (Cat. No. DM1-Y73) is specific to Trastuzumab-DM1 and has no cross-reactivity with Trastuzumab Deruxtecan, Disitamab Vedotin (RC48), Trastuzumab MMAE and Sacituzumab Govitecan (Routinely tested).

FAQ

Can lyophilized proteins remain stable during room-temperature shipping or temporary room-temperature exposure?
In general, lyophilized proteins remain stable during room-temperature shipping or temporary exposure to room-temperature conditions.
Many ACROBiosystems recombinant proteins are supplied in lyophilized (freeze-dried) form. The lyophilization process effectively removes moisture from the product, helping reduce degradation-related reactions and improve protein stability during transportation and storage.
To evaluate the stability of lyophilized proteins under normal temperature conditions, ACROBiosystems conducted a stability study on 11 representative lyophilized protein products at 37°C. The study demonstrated that these proteins maintained good quality stability after storage at 37°C for approximately 20 days. Based on these validation results, temporary room-temperature exposure during shipping or handling is generally not expected to have a significant impact on product quality or downstream application performance.
To ensure optimal long-term stability, products should be stored according to the storage conditions specified in the product Certificate of Analysis (COA) upon receipt.
