Analysis of Plant Acid Invertase (AI) by ELISA (CAT#: STEM-MB-2307-LGZ)

Introduction

Detection range: 6.25 U/L – 200 U/L<br />Sensitivity: minimum detection concentration less than 1.0 U/L.<br />Specificity: does not cross react with other soluble structural analogues.<br />Repeatability: coefficient of variation within the plate was less than 10%, coefficient of variation between the plate was less than 15%.




Principle

Enzyme-linked immunosorbent assay (ELISA) is an enzyme-labeled solid phase immunoassay technique. Its basic principle is to bind the antigen (or antibody) to the solid phase carrier, and the antigen (or antibody) and a certain enzyme link to enzyme labeled antigen (or antibody). During detection, the sample to be tested and the enzymic antigen (or antibody) react with the antigen (or antibody) on the solid phase carrier according to certain procedures, and then remove the unreacted part by washing method. After adding the substrate, the substrate is catalyzed by the enzyme on the solid phase carrier to produce colored substances. Through qualitative or quantitative detection of the amount of colored products, the content of the substance to be measured in the sample can be determined.

Applications

It was used to quantitatively detect the content of plant acid invertase (AI) in tissue, cell and related liquid samples in vitro.

Procedure

1. Add standards or samples to each well and incubate.
2. Pour off the liquid in the well, biotinylated antibody working solution and incubate.
3. Add enzyme conjugate working solution and incubate.
4. Add substrate TMB and incubate.
5. Add stop solution and measure OD value.
6. Calculation of results.
