Scientific Data Images for Human Cystatin C Antibody

Detection of Human Cystatin C antibody by Western Blot.

Detection of Human Cystatin C by Western Blot.

Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, human liver tissue, and human serum. PVDF membrane was probed with 0.25 µg/mL of Goat Anti-Human Cystatin C Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1196) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Cystatin C at approximately 14 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Cystatin C antibody by Western Blot.

Detection of Human Cystatin C by Western Blot.

Western blot shows lysates of human placenta tissue and PC-3 human prostate cancer cell line. PVDF membrane was probed with 2 µg/mL of Goat Anti-Human Cystatin C Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1196) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Cystatin C at approximately 14 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Cystatin C antibody in Human Breast by Immunohistochemistry (IHC-P).

Cystatin C in Human Breast.

Cystatin C was detected in immersion fixed paraffin-embedded sections of human breast using 5 µg/mL Goat Anti-Human Cystatin C Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1196) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm in cells of terminal ductules. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Neutralization

Measured by its ability to neutralize Recombinant Human Cystatin C (0.64 µg/mL, Catalog # 1196-PI) inhibition of Papain (0.1 µg/mL) cleavage of the fluorogenic peptide substrate Z-FR-AMC (100 µM, Catalog # ES009). The Neutralization Dose (ND50) is typically 12-112 µg/mL.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: Cystatin C

Cystatin C is a member of family 2 of the Cystatin superfamily (1). It is involved in processes such as tumor invasion and metastasis, inflammation and some neurological diseases. It inhibits many cysteine proteases such as papain and cathepsins B, H, K, L, and S (2, 3). It is ubiquitous in human tissues and body fluids. A point mutation in the gene coding for the 120 amino acid mature Cystatin C causes a hereditary form of amyloid angiopathy in which the protein variant (Leu68 to Gln) is deposited in the cerebral arteries, leading to fatal cerebral hemorrhage (4). Cystatin C may have additional clinical applications. For example, it is a good marker for glomerular filtration rate (5).
