Prostate Specific Antigen Protein | PSA protein
Eukaryotic Prostate Specific Antigen (PSA)
PBS, pH7.4, containing 0.01% SKL, 1mM DTT, 5% Trehalose and Proclin300.
Stability: 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 degree C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

NCBI and Uniprot Product Information
Accurate Molecular Mass: 35kDa
NCBI Description
Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel cancer and other disease biomarkers. The gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. It encodes a single-chain glycoprotein, a protease which is synthesized in the epithelial cells of the prostate gland, and is present in seminal plasma. It is thought to function normally in the liquefaction of seminal coagulum, presumably by hydrolysis of the high molecular mass seminal vesicle protein. The serum level of this protein, called PSA in the clinical setting, is useful in the diagnosis and monitoring of prostatic carcinoma. Alternate splicing of this gene generates several transcript variants encoding different isoforms. [provided by RefSeq, Dec 2019]
Uniprot Description
PSA: Hydrolyzes semenogelin-1 thus leading to the liquefaction of the seminal coagulum. Forms heterodimer with SERPINA5. Inhibited by SERPINA5. Activity is strongly inhibited by Zn2+, 100 times more abundant in semen than in serum. This inhibition is relieved by exposure to semenogelins, which are avid zinc binders. Belongs to the peptidase S1 family. Kallikrein subfamily.

Product Notes
The PSA klk3 (Catalog #AAA2122441) is a Protein produced from 293F Cell and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is Ala18~Pro261. AAA Biotech's Prostate Specific Antigen can be used in a range of immunoassay formats including, but not limited to, Positive Control, Immunogen, SDS-PAGE, Western Blot (WB). Researchers should empirically determine the suitability of the PSA klk3 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Prostate Specific Antigen, Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
