The ELISA titer of up to four antibody samples is determined (in duplicate) using covalently immobilized antigen or peptide. The titer is expressed as the (inverse) dilution at which the sample exhibited a 0.500 absorbance. The entire range of dilutions is plotted versus absorbance on the provided certificate of completion.

Data Provided

The titer (as defined by the dilution where a 0.500 absorbance is recorded) is calculated and a graph of the entire titration curve is provided.

Additional Information

Please supply approximately 100 µg of antigen. Shipping instructions are included on the quotation.
Peptide must include a terminal (reduced) cysteine. Any peptide made by us will work without further modification.
