稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
运输条件
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
Prostate-Specific Antigen (PSA) is a glycoprotein produced by the epithelial cells of the prostate gland and is predominantly used as a biomarker for prostate cancer detection and monitoring. Elevated PSA levels in the blood can indicate prostate cancer or other prostate-related conditions, making it a critical tool in urology and oncology. However, the specificity of PSA as a tumor marker is often questioned, as benign prostatic hyperplasia and prostatitis can also elevate PSA levels. Consequently, researchers have focused on the recombinant production of PSA for various applications, including better diagnostic tests, therapeutic approaches, and vaccine development. The recombinant PSA can be produced in bacterial or mammalian cell systems, allowing for large-scale production and purification, which is essential for research and clinical uses. Furthermore, studying PSA's structure and function through recombinant techniques provides insights into its role in cancer biology and potential therapeutic mechanisms. As such, the development of PSA as a recombinant protein is paving the way for advancements in prostate cancer diagnosis and treatment, signaling a shift towards more precise and effective management of this prevalent disease.
