Scientific Data Examples for Recombinant Human PHGDH His-tag, CF

	Recombinant Human PHGDH His-tag Enzyme Activity Recombinant Human PHGDH His-tag (Catalog # 10131-DH) is measured by its ability to catalyze the oxidation of 3-phospho-D-glycerate. The activity (orange) is over 2-fold than the competitor's PHGDH (green).
	Recombinant Human PHGDH His-tag SDS-PAGE 2 μg/lane of Recombinant Human PHGDH His-tag (Catalog # 10131-DH) and 2 μg/lane of competitor Human PHGDH was resolved with 4-20 % SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by Coomassie.

Formulation, Preparation and Storage

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: PHGDH

Phosphoglycerate dehydrogenase (PHGDH) catalyzes the oxidation of 3-phospho-D-glycerate to 3-phosphooxypyruvate, which is the first step of the L-serine biosynthesis pathway. Human PHGDH is a Type I NADH-dependent enzyme that forms an active oligomer where each monomer is composed of 4 domains: a substrate-binding domain, a nucleotide-binding domain, and two regulatory domains: ASB (allosteric substrate binding) and ACT (Aspartate kinase, Chorismate mutase, and Tyr A)(1). Serine biosynthesis by PHGDH is the sole source of serine biosynthesis in mammals (2) and conditional knockout confirmed L-serine synthesis by PHGDH is the source of D-serine in the brain (3). PHGDH null mice are embryonic lethal (4) and mutations that lead to PHGDH deficiency have been reported in infantile, juvenile and adult onset phenotypes (5, 6). PHGDH is also suggested to play a role in several cancers including breast (7), cervical (8), melanoma (9), colon (10), pancreatic (11), liver (12), and kidney (13) through increased PHGDH expression and enhanced tumor cell proliferation. Levels of PHGDH correlate with patient survival and may be used as a prognostic factor (14). A mutation resulting in inactive PHGDH (15), cell line knockdown (8, 11), and treatment with enzymatic inhibitors in cancer cells (13) result in decreased proliferation. Given the correlation between high PHGDH and cancer and the results from indirect inhibition of PHGDH activity, PHGDH is a pharmaceutical target for cancer therapy (16-18).
