Performance Data
Bioactivity-ELISA
Immobilized Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212) at 1 μg/mL, add Loncastuximab Tesirine in the 100% Human Serum and then add Biotinylated Human CD19 (20-291), His,Avitag, premium grade (Cat. No. CD9-H82E9) at 0.5 μg/mL. Detection was performed using HRP-conjugated Streptavidin (Acro, Cat. No. STN-NH913) (QC tested).
Protocol
Serial dilutions of (PBD)SG3199 were added into Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212)): Loncastuximab Tesirine binding reactions. The half maximal inhibitory concentration (IC50) is 0.02167 μg/mL (Routinely tested).
Protocol
Cross Verification
ELISA binding of Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212) with Loncastuximab Tesirine, Disitamab Vedotin (RC48), IgG1-MMAF, Trastuzumab Deruxtecan, Sacituzumab Govitecan and Trastuzumab-DM1 conjugated antibody respectively.
The coating antibody was Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212), used at 1 μg/mL concentration. The primary antibody were different payload conjugated antibodies, including Loncastuximab Tesirine, Disitamab Vedotin (RC48), IgG1-MMAF, Trastuzumab Deruxtecan, Sacituzumab Govitecan and Trastuzumab-DM1 conjugated antibodies used at 0.25 μg/mL concentration. The secondary antibody was HRP conjugated Anti-Human-IgG-Fc Antibody (6F11C8), mAb (Acro, Cat. No. IGG-LY69) used at 1:10000 concentration.
Monoclonal Anti-Payload PBD Antibody, Rabbit IgG (1M1F9) (Cat. No. PAD-MY2212) is specific to Loncastuximab Tesirine and has no cross-reactivity with IgG1-MMAF, Disitamab Vedotin (RC48), Trastuzumab Deruxtecan, Sacituzumab Govitecan and Trastuzumab-DM1 (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.
