Description

Multi-Species VA (Vitamin A) ELISA KitThe VA (Vitamin A) ELISA kit uses the Competitive ELISA principle. The micro ELISA plate provided in this kit has been pre coated with Universal VA. During the reaction, Universal VA in the sample or standard competes with a fixed amount of Universal VA on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal VA. Excess conjugate and unbound sample or standard are washed away, and Avidin Horseradish Peroxidase

The VA (Vitamin A) ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Universal VA. During the reaction, Universal VA in the sample or standard competes with a fixed amount of Universal VA on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal VA. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of Universal VA in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Pretty and sturdy little event cups
Size: 50PCS, Color: 14oz Gold Glitter
The perfect little cup for a wedding shower. Loved the look and color and print on these cups and they were an excellent size and thickness to provide durability and as not to leak. Would order these again for future events.

Cute, perfect for party. A little flimsy.
Size: 50PCS, Color: 14oz Gold Glitter
Very cute and perfect for my daughter’s golden birthday celebration. The cups are a little thin and prone to break, but not a huge deal since they’re used at disposal cups anyways.
