Performance Data
Bioactivity-ELISA
The binding activity of Monoclonal Anti-Camelid VHH Antibody, Rabbit IgG (M1A11) (Cat. No. CAH-MY2491a) to different humanized VHHs was evaluated by ELISA. Humanized VHHs were coated at 1 μg/mL. The antibody was serially diluted starting at 31.25 ng/mL, followed by incubation with an HRP-conjugated goat anti-rabbit IgG Fc-specific secondary antibody at a 1:30,000 dilution. Absorbance was measured at 450 nm (Routinely tested).
Protocol
The binding activity of Monoclonal Anti-Camelid VHH Antibody, Rabbit IgG (M1A11) (Cat. No. CAH-MY2491a) to different alpaca VHHs was evaluated by ELISA. Alpaca VHHs were coated at 1 μg/mL. The antibody was serially diluted starting at 31.25 ng/mL, followed by incubation with an HRP-conjugated goat anti-rabbit IgG Fc-specific secondary antibody at a 1:30,000 dilution. Absorbance was measured at 450 nm (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.
