Performance Data
Bioactivity-ELISA
Immobilized Trastuzumab at 1 μg/mL (100 μL/well) can bind Monoclonal Anti-Trastuzumab Antibody, Mouse IgG1 (AY1b) (Cat. No. TRB-Y1b) with a linear range of 0.4-6 ng/mL (QC tested).
Protocol
Immobilized Monoclonal Anti-Trastuzumab Antibody, Mouse IgG1 (AY1b) (Cat. No. TRB-Y1b) at 2 μg/mL, add increasing concentrations of Trastuzumab in the 10% human serum and then add Biotinylated Monoclonal Anti-Trastuzumab Antibody, Mouse IgG1 (6F2F7-2) (Cat. No. TRA-BLY5b) at 2 μg/mL. Detection was performed using HRP-conjugated streptavidin with sensitivity of 48 ng/mL (QC tested).
Protocol
Serial dilutions of Monoclonal Anti-Trastuzumab Antibody, Mouse IgG1 (AY1b) (Cat. No. TRB-Y1b) was detected by Biotinylated Human Her2, His,Avitag (Cat. No. HE2-H82E2) with a half maximal inhibitory concentration (IC50) of 4.58 μg/mL (Routinely tested).

FAQ
- product
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.
