DatasheetSpecific PreferencesReviewsResearch TopicsProtocols
SPARCL1Antibody Product Information
Antigen:Recombinant Human SPARCL1 protein (Catalog#10046-H08H)
Clone ID:6D1D6G5
Ig Type:Mouse IgG1
Formulation:0.2 μm filtered solution in PBS with 5% trehalose
Preparation:This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human SPARCL1 (rhSPARCL1; Catalog#10046-H08H; NP_004675.3; Met 1-Phe 664). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.

Immunofluorescence staining of Human SPARCL1 in A431 cells. Cells were fixed with 4% PFA, permeabilzed with 1% Triton X-100 in PBS, blocked with 10% serum, and incubated with mouse anti-Human SPARCL1 monoclonal antibody (15 µg/ml). Then cells were stained with the Alexa Fluor® 488-conjugated Goat Anti-mouse IgG secondary antibody, countstained with DAPI (blue). Positive staining was localized to cytoplasm.

SPARC-like protein 1 (SPARCL1; also known as SC1, high endothelial venule protein, or hevin) is an extracellular matrix-associated, secreted glycoprotein belonging to the secreted protein acidic and rich in cysteine (SPARC) family of matricellular proteins. It contains three conserved structural domains that are implicated in the regulation of cell adhesion, migration, and proliferation. SPARCL1 is expressed during embryogenesis and tissue remodeling and is especially prominent in brain and vasculature. Its down-regulation in a number of cancers and the possibility of its functional compensation by SPARC has led to recent interest in hevin as a tumor suppressor and regulator of angiogenesis. SPARCL1 has antiadhesive properties, and loss of SPARCL1 expression is associated with increased proliferative activity and cell cycle progression. It is suggested that it may influence multiple cellular processes during distinct stages of brain development and function. In addition, SPARCL1 can influence the function of astroglial cells in the developing and mature central nervous system (CNS).
