Biological Activity

Description

The LDHA protein facilitates the simultaneous and stereospecific interconversion of pyruvate and lactate, accompanied by the concomitant exchange of NADH and NAD(+).LDHA Protein, Rat (His) is the recombinant rat-derived LDHA protein, expressed by E.coli , with N-His labeled tag.

Background

LDHA Protein, an isoform of lactate dehydrogenase, is vital in cellular metabolism, converting pyruvate to lactate for energy production in anaerobic conditions. Understanding LDHA Protein's functions is crucial for studying metabolic disorders and developing therapies targeting altered metabolism in cancer and other diseases.

Verified Bioactivity

Measured by its ability to reduce pyruvate to lactate. The specific activity is 70337.62058 pmol/min/μg, as measured under the described conditions.

Product Properties

Appearance

Lyophilized powder

Formulation

1.Lyophilized from a 0.22 μm filtered solution of 50 mM Tris-HCl, 300 mM NaCl, pH 7.4.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
