2009年2月6日 · This document describes the procedure for the indirect Enzyme Linked ImmunoSorbant Assay (ELISA) that is used to assess the reactivity of the monoclonal antibodies for the recombinant antigens used as immunogens. It is not intended as a procedure for measurement of native antigens.

The enzyme linked immunosorbent assay (ELISA) is a powerful method for detecting and quantifying a specific protein in a complex mixture. Originally described by Engvall and Perlmann (1971), the method enables analysis of protein samples

Enzyme-Linked Immunosorbent Assay (ELISA) 1.1. PHOSPHATE-BUFFERED SALINE (PBS) . *crystalline phosphate salts vary widely in formula weight/molar mass, depending on the amount of water of hydration. Check formula weight of each batch before use and adjust weights used accordingly. 1.2. COATING BUFFER. 1.3. WASHING BUFFER (PBS-TWEEN-20) 1.4.

The purpose of this document is to outline operating procedures for the safe working with Enzyme-Linked Immunosorbent Assay (ELISA) in order to protect laboratory personnel and students from potential risks of infections and other risks in the NUS Department of Medicine research laboratories.

8.1 New reagents should be qualified prior to use in an ELISA procedure. 8.2 By titering new or unknown reagents together with known reagents in a ELISA based assay a optimal concentration for use can be determined for the new component.

ELISA is a powerful, as well as common tool for the detection of antigens in biological samples. In this Module, you will perform a sandwich ELISA with biotin-streptavidin detection. 1. Purpose The purpose of this SOP is to instruct students on the proper procedures involved in the Enzyme-Linked Immunosorbent Assay. 2. Scope

Detailed ELISA protocols cover indirect and capture ELISA techniques, recommending products for sandwich and indirect ELISA experiments.

ELISA (enzyme-linked immunosorbent assay) is a plate-based assay technique designed for detecting and quantifying peptides, proteins, antibodies and hormones. In an ELISA, an antigen must be
