Product Usage Information

This product is the carrier free version of product #92479. 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 Na2HPO4, 3 mM KCl, 2 mM KH2PO4, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

For standard formulation of this product see product #92479

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

Asparagine Synthetase (E6C2C) XP® Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total asparagine synthetase protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Lys467 of human asparagine synthetase protein.

Background

Asparagine synthetase (ASNS) catalyzes the synthesis of asparagine from aspartate and glutamine. Research studies have shown that intracellular asparagine can suppress apoptosis in a large number of human tumors. In addition, ASNS expression levels have been associated with the progression of gliomas and neuroblastomas in patients (1). Furthermore, acute lymphocytic leukemia cells frequently depend upon serum asparagine for their viability, as they lack ASNS (2). Deprivation of asparagine by L-asparaginase has therefore been developed as a therapeutic treatment for acute lymphocytic leukemia (2,3). In subsets of gastric and hepatic cancers, ASNS promoter hypermethylation correlates with low ASNS expression, sensitizing these cancers to the asparaginase treatment (4).
