Data Examples
Detection of Human SPARC‑like 1/SPARCL1 by Western Blot. Western blot shows lysates of human lung tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human SPARC‑like 1/
SPARCL1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2728) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for SPARC‑like 1/SPARCL1 at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Immunohistochemistry
SPARC‑like 1/SPARCL1 in Human Brain. SPARC‑like 1/SPARCL1 was detected in immersion fixed paraffin-embedded sections of human brain using Goat Anti-Human SPARC‑like 1/SPARCL1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2728) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to neurons.

Intracellular Staining by Flow Cytometry
Detection of SPARC‑like 1/SPARCL1 in HL‑60 Human Cell Line by Flow Cytometry.

HL‑60 human acute promyelocytic leukemia cell line was stained with Goat Anti-Human SPARC‑like 1/SPARCL1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2728, filled histogram) or control antibody (Catalog # AB-108-C, open histogram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0107).  To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Background: SPARC-like 1/SPARCL1

SPARCL1 (Secreted Protein, Acidic and Rich in Cysteines-like 1), also known as hevin, SC1 or MAST9, is a member of the SPARC family of extracellular glycoproteins (1, 2). SPARCL1 is an anti-adhesive protein that is widely expressed in tissues such as brain, heart, lung, muscle and kidney, but not liver (3, 4). Human SPARCL1 contains a 16 amino acid (aa) signal sequence and a 648 aa mature region with four domains: a 416 aa N-terminal acidic region, a 23 aa follistatin-like domain, a 55 aa kazal-like segment and a 48 aa EF-hand/calcium-binding domain (3, 4). SPARCL1 is predicted at 75 kDa, but migrates at ~130 kDa, which has been explained either by disulfide-linked homodimerization or by glycosylation and high acidity (3-5). Some truncated forms have been reported. In mouse, a 55 kDa C-terminal fragment is the only form in kidney and represents a portion of SPARCL1 in other tissues (6). In humans, a 25 kDa form is increased in liver tumors that are encapsulated, while the full-length form is downregulated in many epithelial cell-derived tumors (7, 8). SPARCL1 inhibits adhesion and spreading on a variety of substrates (5, 9). It is thought to cause antiadhesive signaling that terminates neuronal migration, consistent with production by glial and neuronal cells during development or in response to trauma (10). In tonsillar high endothelial venules (HEV), SPARCL1 may induce endothelial cell dissociation, promoting extravasation (3). SPARCL1 binds collagen; in mice, deletion causes dermal collagen fibrils that are smaller in diameter and deficient in decorin (6, 11). Human mature SPARCL1 shares 67%, 69%, 78%, 76%, 72%, and 72% aa identity with mouse, rat, equine, canine, porcine and bovine SPARCL1, respectively. The follistatin-like, kazal-like and calcium-binding domains of SPARCL1 show 61% aa identity with corresponding regions of SPARC.
