Lithium Pyruvate Monohydrate [Guaranteed for Standard to GOT, GPT] TCI P0659

Lithium Pyruvate Monohydrate from TCI (product code P0659, CAS 2922-61-4) is the lithium salt of pyruvic acid in monohydrate form. This grade is guaranteed for use as a standard in GOT and GPT measurements. GOT (glutamate oxaloacetate transaminase, also called AST) and GPT (glutamate pyruvate transaminase, also called ALT) are enzymes whose activity is routinely measured in clinical biochemistry. Pyruvate is a key compound in transaminase reactions, so this material is an important reference substance for building calibration curves in methods that determine the activity of these enzymes.

The lithium salt form is used because it is a solid that is more stable and easier to weigh than free pyruvic acid, which tends to be unstable. This makes it practical to prepare reference solutions consistently and accurately in the laboratory. The "Guaranteed for Standard to GOT, GPT" grade shows that the product's quality is intended specifically for this analytical standard purpose, so calibration results are more reliable. TCI's consistent documentation and quality control support reproducible work across repeated analytical runs and between different analysts in the same laboratory.

In Indonesian laboratories, this material is mainly relevant to clinical chemistry, biochemistry, and analytical research facilities that work with transaminase activity assays or develop and validate such methods. University research groups and teaching laboratories may also use it to show how calibration standards work in enzyme analysis. The catalog also lists the product under battery electrolyte materials because it contains lithium, but its best-established role, as the grade name indicates, is as a biochemical standard. Researchers should match its use to their own needs and verify that it is suitable.

• Calibration standard for GOT (AST) assays: this guaranteed grade provides a reliable pyruvate reference for building calibration curves when determining the activity of glutamate oxaloacetate transaminase.
• Calibration standard for GPT (ALT) assays: pyruvate is a key compound in the transaminase reaction, so this material serves as a suitable reference when measuring glutamate pyruvate transaminase activity in biochemical methods.
• Method development and validation in clinical biochemistry: the stable, easy-to-weigh lithium salt supports consistent preparation of reference solutions when laboratories develop, verify, or compare enzyme activity procedures.
• Teaching and training in enzyme analysis: university laboratories can use this standard to show students how calibration curves are built and interpreted in transaminase activity measurements.
• Exploratory materials research involving lithium compounds: because the catalog lists it under battery electrolyte materials, researchers may consider it for screening work, but they must verify its suitability for that purpose themselves.

• Grade: Guaranteed for Standard to GOT, GPT

Keep this product in its original, tightly closed manufacturer container in a cool, dry place away from direct sunlight, heat, and moisture. Follow the storage temperature and conditions on the TCI label and Safety Data Sheet. Because it is used as an analytical standard, prevent contamination: use clean, dry spatulas and glassware, and close the container right after use. Weigh it promptly so it does not pick up moisture from the air. Wear appropriate personal protective equipment, such as gloves, safety glasses, and a lab coat, and avoid creating or breathing in dust. Record the opening date, and dispose of waste according to local regulations and institutional laboratory procedures.
