CST, 81977SF, 4F2hc/SLC3A2 (D3F9D) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying SLC3A2/CD98hc. Validated for WB,IHC,IF,F,F. Highly specific and rigorously validated in-house, 4F2hc/SLC3A2 (D3F9D) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #81977) is ready to ship. Product Usage Information This product is the carrier free version of product #47213. 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 # 47213 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 4F2hc/SLC3A2 (D3F9D) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total 4F2hc/SLC3A2 protein. This antibody is predicted to detect multiple isoforms of 4F2hc/SLC3A2. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val509 of human 4F2hc/SLC3A2 protein. Background 4F2hc is a transmembrane protein that belongs to the solute carrier family. 4F2hc forms heterodimeric complexes with various amino acid transporters such as LAT1 and LAT2 and regulates uptake of amino acids (1-5). 4F2hc is one of the earliest expressed antigens on the surface of activated human lymphocytes (6), hence it is also named CD98. 4F2hc is expressed in all cell types with the exception of platelets, and is expressed at highest levels in the tubules of the kidney and the gastrointestinal tract (7,8). It is localized at the plasma membrane when associated with LAT1 or LAT2 (9) and at the apical membrane of placenta (10). Research studies have shown that 4F2hc is highly expressed in various tumors including glioma (11), ovarian cancer (12), and astrocytomas (13), and it has been implicated in tumor progression and correlated with poor outcome in patients with pulmonary neuroendocrine tumors (14). 4F2hc is also involved in integrin trafficking through association with β1 and β4 integrins, and regulates keratinocyte adhesion and differentiation (15).
