The Use of the Enzyme Linked Immunosorbent Assay to Detect a Nuclear Polyhedrosis Virus in Heliothis armigera Larvae

Fabrication of a Voltammetric Biosensor in Combination with Enzyme-linked Immunosorbent Assay to Detect Aflatoxin M1 in Milks

Background and Objectives: Aflatoxin M1 is one the most important mycotoxin contaminants of milks. Various methods have been described to detect aflatoxins in milks, including chromatography, enzyme-linked immunosorbent assay and colorimetry. Regarding high sensitivity of electrochemical sensor based methods, the aim of the present study was to fabricate an accurate sensitive voltametric biosen...

Development of an Indirect Enzyme-linked Immunosorbent Assay to Detect Antibodies against Serotype A2013 of Foot and Mouth Disease Virus in Cattle

Foot and mouth disease (FMD) is a contagious animal disease that causes irreparable damage to the economy of countries, including Iran in which this disease is a native one. Among the ways to combat FMD are vaccination and slaughter. Due to the specific situation of Iran, it is not possible to kill infected animals. Therefore, vaccination is the most important way to fight this disease. S...

ENZYME-LINKED IMMUNOSORBENT ASSAY OF NEOPTERIN USING PENICILLINASE AS LABEL

An enzyme-linked immunosorbent assay for neopterin using penicillinase as marker enzyme is reported here by polyclonal antibodies against neopterin conjugated to bovine serum albumin which were raised in rabbits. Immunoglobulin fractions were purified and coated on wells of microtiter plates. A chain heterology was introduced in neopterin derivative and conjugated to penicillinase. The assa...

Enzyme - Linked Immunosorbent Assay to Detect the Sendai Virus Infection in Mice

Standardization of an Enzyme-Linked Immunosorbent Assay for Detection of Infectious Bronchitis Virus Antibody.

An indirect enzyme–linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectious bronchitis virus (IBV). Antigen was prepared from whole-purified IBV Massachusetts serotype (BR 801 strain). Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed ELISA was determined 0.1μg/ml, 1:3000 and 1:100, respe...
