Vitamins B1 and B6 in Whole Blood, with 96 Well Filter Plates – HPLC Reagent Kit

Order No.: 52752/F, for 960 tests
Parameters:
Vitamin B1 (TPP, thiamine pyrophosphate), Vitamin B6 (PLP, pyridoxal 5’-phosphate)

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

Assay validated according to IVDR (=> Declaration of Conformity)

Vitamin B1 (TPP, thiamine pyrophosphate)

Vitamin B6 (PLP, pyridoxal 5’-phosphate)

Clinical relevance
This assay allows the quantitative determination of the physiologically active forms of vitamin B1, thiamine pyrophosphate, and of vitamin B6, pyridoxal 5‘-phosphate, in human whole blood samples.

It is intended to be used for for screening and/or monitoring of vitamin B1 and/or B6 levels where indicated
• in patients with suspected vitamin B1 and/or B6 deficiency,
• in patients with suspected vitamin B1 and/or B6 excess,
• in patients under vitamin B1 and/or B6 supplementation therapy.

 

Product advantages
• Specific internal standard for each parameter
• No post-column derivatisation required
• One sample preparation and one run for both parameters

 

Assay characteristics
Thiamine pyrophosphate (TPP) and pyridoxal 5’-phosphate (PLP) can be determined 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 and is possible with Reaction Vials (assays 52052 and 52052/Premix) or 96 Well Filter Plates (assay 52752/F). Pre-mixed Neutralisation Tubes simplify sample preparation when performing the 52052/Premix assay. Chromatographic separation is carried out with two Mobile Phases by HPLC. The derivatised analytes are determined by fluorescence detection with wavelength switching. The use of two internal standards assures high precision and safety in quantifying the analytes.
