Vitamin B1 in Whole Blood and Vitamin B6 in Whole Blood/Plasma - HPLC

Order No.: 52052/RUO, for 100 tests
Parameters:
Vitamin B1 (TPP, thiamine pyrophosphate), Vitamin B6 (PLP, pyridoxal 5’-phosphate)

Each analyte safeguarded by a specific internal standard
No post-column derivatisation required
One sample preparation and one run for both analytes

Vitamin B1 (TPP, thiamine pyrophosphate)

Vitamin B6 (PLP, pyridoxal 5’-phosphate)

This Chromsystems reagent kit allows for the HPLC determination of thiamine pyrophosphate and pyridoxal-5’-phosphate, analogues of Vitamin B1 and Vitamin B6, in one run, with one sample preparation and without complex post-column derivatisation. Sample preparation is restricted to a single precipitation step and subsequent derivatisation in a reaction vial. The derivatised research sample is analysed using fluorescence detection with a wavelength switching, and the chromatographic separation is performed with 2 mobile phases in less than 9 minutes. The use of a tailor-made internal standard for each parameter ensures precise and accurate results.

Sample Preparation
  • In a light protected vial mix 200 μl whole blood or plasma with 100 μl Internal Standard and 300 μl Precipitation Reagent, mix for at least 30 sec (vortex).

  • Centrifuge for 5 min with at least 9000 x g.

  • In a new light protected vial mix 250 μl Neutralisation Reagent and 100 μl Derivatisation Mix with 250 μl supernatant obtained above, mix briefly.

  • Incubate for 25 min at 60 °C (waterbath).

  • Cool sample for 10 min at +2 to +8 °C, then centrifuge for 2 min with at least 9000 x g.

  • Transfer supernatant into a light protected autosampler vial, inject 25–50 μl into the HPLC system.

Sample Stability The research samples are stable at +2 to +8°C for 1day. For longer storage (up to 1week) deep freeze the research samples below -18°C (maximum 2 weeks).
