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: MDH1

Malate Dehydrogenase 1 (MDH1), also known as aromatic alpha-keto acid reductase, belongs to the family of nicotinamide adenine dinucleotide (NAD)-dependent dehydrogenases and is a key enzyme in the malate-aspartate shuttle where it plays a critical role in the regulation of metabolic activity in humans (1, 2). MDH1 is an active homodimer of monomers that each contain the characteristic conserved Rossman fold, similar NAD binding sites, and dimeric quaternary structure of MDH enzymes (3). MDH is ubiquitously expressed in cells in two separate isoforms that differ in cellular localization and share only 26% sequence homology (3). While MDH2 is a mitochondrial form involved in the regulation of mitochondrial NAD levels within the citric acid cycle, MDH1, the cytosolic form, plays an important role in the regulation of cytosolic NAD levels. Increased cytosolic NAD levels are necessary for maintaining enhanced glycolysis of proliferating cancer cells (4) and MDH1 is overexpressed in tumors and correlated with poor prognosis (5-8). In addition, MDH1 has been found to serve as a potential marker in several diseases with inflammation and deficiency of MDH1 is associated with early onset severe encephalopathy and associated with acute liver failure (2, 9-11) making it a metabolic therapeutic target of interest with several potential applications (1, 3, 6, 12, 13).
