How ELISA data is used to produce a sigmoidal curve?
- ELISA data is typically graphed with optical density vs log concentration to produce a sigmoidal curve as shown below. Known concentrations of antigen are used to produce a standard curve and then this data is used to measure the concentration of unknown samples by comparison to the linear portion of the standard curve.
What is a semi-quantitative ELISA?
- Semi-Quantitative: ELISAs can be used to compare the relative levels of antigen in assay samples, since the intensity of signal will vary directly with antigen concentration. ELISA data is typically graphed with optical density vs log concentration to produce a sigmoidal curve as shown below.
How many reagents are in a ELISA kit?
- Each of our ELISA kits has sufficient reagents for 96 tests per kit. The table below shows some of the most commonly used ELISA kits. Cell Culture Supernates [CCS], Serum [Se], Plasma: Heparin [P(h)], Plasma: EDTA [P(e)], Plasma: Citrate [P(c)], Urine [U], Milk [M], Cell Lysate (CL), Tissue (T) Lyophilized recombinant standard (1 ng to 100 ng)
What is a standard capture or sandwich ELISA?
- This protocol represents an example of a standard capture or sandwich ELISA using a biotinylated detection antibody and streptavidin-HRP indirect detection system with commonly used reagents and TMB (tetramethyl benzene) substrate. For other ELISA variations, see the section entitled Modifications to the ELISA Protocol at the end of this procedure.
