Step by step
Solved in 2 steps
- Briefly explain why this is ELISA referred to as colorometric assay.Conjugated enzymes are a key component of ELISA. To what are these enzymes conjugated, and why is that important? To the antigen so the enzymes are only present when the molecule of interest is also present To the plastic of the reaction well so the enzymes can concentrate the molecule of interest To the capture antibody so the enzymes are only present when the molecule of interest is also present To the detection antibody so the enzymes are only present when the molecule of interest is also presentIn relation to ELISA technique, fill in the missing information in the figure below: 1- 2- 3- 4-
- In the “sandwich” ELISA technique, what is the function of the capture antibody? In the “sandwich” ELISA technique, what is the function of the capture antibody? To link an enzyme and the molecule of interest To convert a substrate from colorless to blue To block any “open spaces” on the well before adding the samples that potentially contain the molecule of interest To concentrate the molecule of interestWhat is the difference between an indirect ELISA and a sandwich ELISA? Is rapid antibody testing a form of ELISA?what is the principle of ELISA? What is the procedure of direct and indirect ELISA and what is the purpose of each variant in clinical diagnosis?
