The SPARC  sparc (Catalog #MBS2544117) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Rabbit anti Human SPARC  Monoclonal Antibody reacts with Human and may cross-react with other species as described in the data sheet. MyBioSource\'s SPARC  can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA).
ELISA: 0.1-0.2 mug/mL. This antibody can be used at 0.1-0.2 mug/mL with the appropriate secondary reagents to detect Human SPARC. The detection limit for Human SPARC is approximately 0.00975 ng/well. Researchers should empirically determine the suitability of the SPARC  sparc for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process.

The SPARC  sparc product has the following accession number(s) (GI #4507171). Researchers may be interested in using Bioinformatics databases such as those available at The National Center for Biotechnology Information (NCBI) website for more information about accession numbers and the proteins they represent. Even researchers unfamiliar with bioinformatics databases will find the NCBI databases to be quite user friendly and useful.

Secreted protein acidic and rich in cysteine (SPARC), also known as Osteonectin (ON), is a member of the SPARC family. SPARC consists of three domains: an EF-hand domain, a follistatin-like domain and a Kazal-like domain, and each of which has independent activity and unique properties. The activity of SPARC is context- and cell-type-dependent, which is highlighted by the fact that SPARC has shown seemingly contradictory effects on tumor progression in both clinical correlative studies and in animal models. The location of SPARC in the nuclear matrix of certain proliferating cells, but only in the cytosol of postmitotic neurons, indicates potential functions of SPARC as a nuclear protein, which might be involved in the regulation of cell cycle progression and mitosis. It functions not only to modulate cell-cell and cell-matrix interactions, but its de-adhesive and growth inhibitory properties in non-transformed cells have led to studies to assess its role in cancer. Its divergent actions reflect the complexity of this protein, because in certain types of cancers, such as melanomas and gliomas, SPARC is associated with a highly aggressive tumor phenotype, while in others, mainly ovarian, neuroblastomas and colorectal cancers, SPARC may function as a tumor suppressor. Recent studies have also demonstrated a role for SPARC in sensitizing therapy-resistant cancers. Notably, SPARC is linked to human obesity.

SPARC  sparc

Immunogen: Recombinant Human SPARC protein
Buffer: 0.2 mum filtered solution in PBS with 5% trehalose. In general, we may offer more than one antibody to a given target to enable options for the researcher. Available antibodies recognizing SPARC  are readily searchable from our website. Different antibodies against the same target such as SPARC  may be optimized or tested for different applications and species. This enables researchers to select the option that may be best for their model system, to screen more than antibody to determine which one may be best for their model system, as well as to use more than one antibody to follow up on and validate their results.
