Vitamin B9 (Folic Acid) Test Kit for dairy products, fruit juice, drinks, bakery food, cereals, wheat flour

This kit is used for quantitative analysis of Folic Acid (Vitamin B9, VB9) in food matrices (added and native). This kit can run 96 tests.

Order No.: WC0014

【Principles】

Vitamin B9 (Folic Acid) Test Kit used microbiology method to detect the volume of Folic Acid in food matrices. Folic Acid supplies the growth of Lacticaseibacillus rhamnosus. Its growth rate associated with the volume of Folic Acid within the sample. Take the Folic Acid medium (Lacticaseibacillus rhamnosus added), samples or Standards and add to the microwell. Incubate at 37℃ and avoid light exposure. Lacticaseibacillus rhamnosus will start growing until Folic Acid are consumed entirely. It takes 44-48 hours to complete incubation. Use microplate reader to read the sample turbidity with 610-630nm or 540-550nm filter. The volume of Folic Acid in sample can be determined by comparing the sample turbidity with the Standards.

Immunoaffinity Column for Aflatoxin B1,B2,G1,G2

The immunoaffinity column can selectively adsorb aflatoxins (B1, B2, G1, G2) from the sample solution, thereby purifying the sample. The purified sample solution can then be directly used for HPLC or LC-MS/MS analysis.Affinity columns can be used in combination with HPLC or LC-MS/MS to achieve rapid testing, and to increase signal-noise ratio  and improve the accuracy of the detection method.

Immunoaffinity Column for 2-in-1 Aflatoxins (B1,B2,G1,G2) and Ochratoxin A

The immunoaffinity column can selectively adsorb aflatoxin (B1, B2, G1, G2) and Ochratoxin A from the sample solution, thereby having a highly targeted purification effect on the sample. The sample  solution that has been purified by passing through the affinity column can be directly used for HPLC analysis or for LC-MS/MS analysis after concentrating with nitrogen gas and resuspended.Order No.: HCM3725B/HCM3750BProduct Properties: AFT B1/B2/G1/G2 300ng, OTA 100ngSpecifications: 3mL,25T/50T
