Descrição

Descrição geral

C-peptide, also known as the connecting peptide, is a 31-amino-acid polypeptide connecting insulin′s A-chain to its B-chain in the proinsulin molecule. Measurement of C-peptide blood serum levels can be used to distinguish between diabetes or hypoglycemia conditions with similar clinical features. This certified Snap-N-Spike^® solution of the fully-intact c-peptide protein is suitable for use as starting material in calibrators and controls in LC-MS/MS c-peptide testing methods.

This certified reference material (CRM) is a primary standard. It is traceable to the SI and higher order standards from National Institute of Standards and Technology (NIST) through an unbroken chain of comparisons. This C-Peptide (human) acetate salt is available as a solution of a pure substance in phosphate buffered saline with a pH of 7.4.

Aplicação

C-Peptide solution is suitable for analytical and R&D applications for in vitro identification, calibration, and quantification.

Características e benefícios

• The total C-Peptide content is quantitatively determined using amino acid analysis (AAA) and HPLC/UV/MS, including unmodified, isomers, and pyroglu species, establishing traceability through the calibration of certification techniques.
• Each raw material used in the preparation of this standard has undergone thorough identification and characterization using multiple analytical techniques.
• The gravimetric preparation of this standard follows ISO 17025 requirements, utilizing qualified and calibrated balances.
• Fill volume conformity is ensured throughout the dispensing process by gravimetric verification using qualified and calibrated balances.
• Long-term stability under freezer storage (-10 °C to -25 °C) conditions has been evaluated.

Nota de preparo

• Thaw the product in the refrigerator or at room temperature.
• Ensure thorough mixing before use.
• Avoid refreezing the product once it has thawed.
• For accurate results, quantitatively transfer the desired volume using established good laboratory practices.
• Use the transferred product to spike into the matrix or dilute it to achieve the desired concentration.
