Source
Biotinylated Human PSMA, His,Avitag, premium grade (PSA-H82Qb) is expressed from human 293 cells (HEK293). It contains AA Lys 44 - Ala 750 (Accession # Q04609-1).
Predicted N-terminus: His
It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

LikesI have several Scientists that use Acro Proteins. We used to order these on Fisher, however, I have now changed to directly through Acro as their ordering is so much easier and they fulfill order promptly and perfectly. We are starting to use more Acro products and I am excited to continue to work with this company and keep getting the same great quality of products, ease of ordering, and super quick fulfillment.- T***n2023-06-29 LikesI ordered this product on Monday and received it by Friday! The product came neatly packed in dry ice with secure packaging. The reagent gave me good standard curves as I titrate the concentration of PSMA for my assay. I will order again next time.
- T***n2021-09-22 LikesI highly recommend for this supplier company .I received this order on Sep . 03 /2021 with enough dry ice for - 80C. Thank you acrobiosystems.
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.
