HM-PR_03-6Vitamin Assay Medium

HiMedia has a wide range of Vitamin Assay Media which are recommended for quantification of vitamins such as folic acid, niacin, pantothenic acid, vitamin B12 etc.
Three categories of media available with HiMedia i.e. Inoculum preparation, Culture maintenance and Assay medium have compositions conforming to pharmacopeia specifications. Maintenance Media contains all necessary nutrients for preserving, maintaining and carrying the stock cultures. Inoculum Media contains nutrients for the propagation of culture prior to use. Assay Medias are intended to quantify vitamin concentrations in unknown, against known standard concentration, by using microbiological assay methods. By using recommended standard ATCC strains, the material under assay is determined by adding appropriate concentration of the test substance to the basal medium and comparing the growth response obtained with that of standard. It can be performed by either of these methods; turbidimetric method or cylinder plate method or cup plate method.
HiMedia含有多種維生素檢測培養基，推薦用於維生素，如葉酸，菸酸，泛酸，維生素B12等.
HiMedia提供的三類培養基即接種物製備，培養維持和分析培養基均符合以下要求：藥典規格。維護培養基含有保存，維持和攜帶原種培養物所需的所有營養素。接種培養基含有在使用前繁殖培養物的營養素。 Assay Medias旨在通過使用微生物測定方法來量化已知標準濃度的未知維生素濃度。通過使用推薦的標準ATCC菌株，通過將適當濃度的測試物質添加到基礎培養基中並將獲得的生長響應與標準品的生長響應進行比較來確定測定中的材料。它可以通過這些方法中的任何一種來執行;比濁法或圓筒板法或杯板法。
