Human Kallikrein 3/PSA Antibody

Antibody type

Polyclonal

Description

Antigen Affinity-purified. Detects human KLK3 in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross-reactivity with recombinant human (rh) KLK2 is observed and less than 5% cross-reactivity with rhKLK1, rhKLK4, rhKLK5, rhKLK7, rhKLK8, rhKLK9, rhKLK10, rhKLK11, rhKLK12, rhKLK13, and rhKLK15 is observed.

Experimental details

Detection of Human Kallikrein 3/PSA by Western Blot. Western blot shows lysates of Recombinant Human Kallikrein 3/PSA (Catalog # 1344-SE), DU145 human prostate carcinoma cell line, and LNCaP human prostate cancer cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human Kallikrein 3/PSA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1344) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Kallikrein 3/PSA at approximately 28-30 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human Kallikrein 3/PSA by Western Blot. Western blot shows lysates of human prostate tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Kallikrein 3/PSA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1344) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Kallikrein 3/PSA at approximately 31 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Kallikrein 3/PSA in LNCaP and MCF-7 Human Cell Lines. Kallikrein 3/PSA was detected in immersion fixed LNCaP human prostate cancer cell line (positive control, left panel) and MCF-7 human breast cancer cell line (negative control, right panel) using Goat Anti-Human Kallikrein 3/PSA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1344) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm of LNCaP cells. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Kallikrein 3/PSA in Human Kidney Cancer Tissue. Kallikrein 3/PSA was detected in immersion fixed paraffin-embedded sections of human kidney cancer tissue using Goat Anti-Human Kallikrein 3/PSA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1344) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of cells in convoluted tubules. View our protocol for Chromogenic IHC Staining of immersion fixed paraffin-embedded Tissue Sections.
