Product Description
Monoclonal Antibody for studying SHPS1. Validated for WB,IHC,IHC,IF,F. Highly specific and rigorously validated in-house, SIRP alpha/SHPS1 (D6I3M) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #47027) is ready to ship.
Product Usage Information
This product is the carrier free version of product #13379. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN, or CUT&Tag assays. If you require a carrier-free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.
Formulation
Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 13379 .
Storage
Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.
Specificity / Sensitivity
SIRP alpha/SHPS1 (D6I3M) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total SHPS1 protein. This antibody recognizes both large and small isoforms of murine mSHPS1/SIRPα.
Species Reactivity: Human, Mouse, Rat, Monkey
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro413 of human SIRPα/SHPS1 protein.
Background
SHP-substrate 1 (SHPS1, SIRPα) is a single-pass membrane protein and member of both the immunoglobulin superfamily and the signal regulatory protein (SIRP) family. Following growth hormone stimulation or integrin binding, SHPS1 is phosphorylated at several tyrosine residues within its cytoplasmic tail. These phosphorylation events promote association between SHPS1 and multiple signaling proteins, including SHP-1, SHP-2, Grb2 and Shc via their SH2 domains (1-4). Recruitment of SHP-1 and SHP-2 results in SHPS1 dephosphorylation and suppression of tyrosine kinase signaling (1-3,5). The tyrosine kinase JAK2 associates with SHPS1 via its carboxy terminus and phosphorylates SHPS1 in response to extracellular stimuli (5). Research studies show that Src associates with and may phosphorylate SHPS1 in response to insulin (4). In macrophages, SHPS1 can form a complex with the Src pathway adaptor protein SKAP2, Fyn-binding protein FYB, and the tyrosine kinase PYK2 (6). The SHPS1 extracellular domain contains at least three IgG-like domains that interact with CD47, a ubiquitously expressed, integrin-associated protein that acts as a repressive cue in both immune and neuronal cells (7,8). The interaction between CD47 and SHPS1 on opposing cells can inhibit cellular migration (9), promote "tethering" between macrophages and target cells during engulfment (10), facilitate self versus non-self recognition (11), and maintain immune homeostasis (12). SHPS1 plays a critical role in modulating the immune response and inflammation, and may play a role in neuronal development (13,14). The interaction between SHPS1 and CD47 may be an exploitable target in cancer therapy (15-17).
