Vitamin A (VA) ELISA Kit

From Assay Genie, this Competitive ELISA Kit is designed for the precise measurement of vitamin A levels in biological samples including serum, plasma, lysate samples, and tissue homogenates. The Vitamin A (VA) ELISA Kit is intended for research use only, supporting studies on metabolism, deficiency disorders, and the impact of supplementation.

Vitamin A plays a vital role in maintaining healthy vision, immune function, and cell growth and differentiation. Deficiencies have been linked to night blindness, impaired immune response, and skin problems, and accurate measurement supports research into these conditions and targeted interventions.

The quoted detection range is 0.156-10 ng/mL, with reactivity described as General and detection method Competitive. Optical density is read at 450 nm using a microplate reader. Kit components include a dismountable ELISA Microplate (8×12 strips), Lyophilized Standard, Sample Diluent, Assay Diluent A and B, Detection Reagent A and B, Wash Buffer, Substrate, Stop Solution, and Plate Sealer. Most components are stored at -20°C, with the Wash Buffer, Substrate and Stop Solution kept at 4°C.
