Performance Data
Bioactivity-Flow Cytometry
5e5 of Anti-PSCA CAR-293 cells were stained with 100 μL of 1:20 dilution (5 μL stock solution in 100 μL FACS buffer) of Alexa Fluor™ 488-Labeled Human PSCA Protein, His Tag (Site-specific conjugation) (Cat. No. PSA-HA2H3) and negative control protein respectively. AF488 signal was used to evaluate the binding activity (QC 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.
