Sulfanethazine (SM2) is wide use antibiotic, which has remarkable effect on controlling and curing livestock and poultry diseases. But it is easy to remain in animal body; also has considerable side effect on human, which can cause faint, headache, exhaust, nausea, vomit,etc; lead to hemolytic anemia, a vacuity of granulocyte, allergic reaction and damage urinary and nervous system; cause the increasing tolerance of drugs. It was regulated that maximum Sulfanethazine residue limit in animal food and feed is 100ppb in America, China, the EU.
Sulfanethazine (SM2) is determined by enzyme immunoassay, shows considerable advantages regarding sensitivity,detection limit, technical equipment and time requirement. It is possible to detect sulfamethazine in egg, honey, milk, urine, serum, muscle and liver.
All reagents required for the enzyme immunoassay-including stands-are contained in the test kits.
The test kit is sufficient for 96 determinations(including stands)
