Recombinant Rat Kallikrein-3/PSA Protein，His

Kallikrein-3, also known as Prostate-Specific Antigen (PSA), is a serine protease encoded by the KLK3 gene and primarily expressed in the prostate. Its discovery and subsequent role as a biomarker for prostate cancer diagnosis and monitoring have been pivotal in the field of urology. Elevated PSA levels in serum are often associated with prostate malignancies, leading to its use in screening and management protocols. However, PSA is not exclusively a cancer marker, as benign prostatic hyperplasia and prostatitis can also raise PSA levels, complicating its clinical utility. The recombinant production of Kallikrein-3 has enabled significant advancements in research and therapeutic applications. By generating large quantities of pure, functional PSA, scientists can conduct detailed studies on its biochemical properties, interactions with various molecules, and its role in prostate cancer progression. Furthermore, recombinant PSA is essential for developing more precise diagnostic tools and evaluating new therapeutic approaches, including anti-PSA antibodies and targeted therapies. As research continues, understanding the nuances of Kallikrein-3 will likely lead to enhanced strategies for early cancer detection, individualized treatment options, and improved patient outcomes in prostate cancer management. The ongoing exploration of Kallikrein-3's functions and mechanisms underscores the importance of this protein in both basic research and clinical applications in oncology.
