Background of Kallikrein 3/PSA

Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), is a glycoprotein enzyme encoded in humans by the KLK3 gene. KLK3 is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland. This gene is mapped to 19q13.33. KLK3 is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer or other prostate disorders. KLK3 is produced for the ejaculate where it liquifies the semen in the seminal coagulum and allows sperm to swim freely. It is also believed to be instrumental in dissolving the cervical mucous cap, allowing the entry of sperm. It is not a unique indicator of prostate cancer, but may also detect prostatitis or benign prostatic hyperplasia.

Antibody Validation

Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence and ELISA with known positive and negative samples to ensure specificity and high affinity.

1 Customer Q&As for Anti-Prostate Specific Antigen/KLK3 Antibody Picoband™


We are currently using anti-Prostate Specific antigen/KLK3 antibody PB9259 for human tissue, and we are well pleased with the WB results. The species of reactivity given in the datasheet says human, rat. Is it true that the antibody can work on horse tissues as well?

Asked: 2020-01-30


The anti-Prostate Specific antigen/KLK3 antibody (PB9259) has not been validated for cross reactivity specifically with horse tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in horse you can get your next antibody for free. Please contact me if I can help you with anything.
