Bioactivity-Flow Cytometry
Flow cytometric analysis of HEK293/Human CD19 Stable Cell Line staining with PE-Labeled Monoclonal Anti-Human CD19 Antibody, Mouse IgG2a (FMC63) (Cat. No. FM3-PCFM7) at 1:50 dilution (2 μL of the antibody stock solution corresponds to labeling of 1e6 cells in a final volume of 100 µL), compared with isotype control antibody. PE signal was used to evaluate the binding activity (QC tested).
Protocol
Non-specificity of PE-Labeled Monoclonal Anti-Human CD19 Antibody, Mouse IgG2a (FMC63) (Cat. No. FM3-PCFM7) binding to CD3+ cells present in human PBMC. Human PBMCs were simultaneously stained with FITC-labeled anti-CD3 antibody and PE-Labeled Monoclonal Anti-Human CD19 Antibody, Mouse IgG2a (FMC63) (2 μL of the antibody stock solution corresponds to labeling of 5e5 cells in a final volume of 100 µL), washed and then analyzed with FACS. Both FITC and PE positive signals was used to evaluate the non-specific binding activity to human CD3+ cells (Routinely tested).

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.
