1. Qualitative Chicken Influenza A Virus Subtype H5N1 Antigen H5N1Ag ELISA Kit Cat No MBS9311007 Store All Reagents At 2 C 8 C Package Size 48T Kit or 96 T Kit Valid Period Six Months 2 C 8 C IN VITRO RESEARCH USE ONLY NOT FOR THERAPEUTIC OR DIAGNOSTIC APPLICATIONS 1 INTENDED USE For the qualitative determination of activated Chicken Influenza A Virus Subtype H5N1 Antigen H5N1Ag in serum plasma tissue homogenate cell culture supernates and other biological fluids 2 PRINCIPLE OF THE ASSAY The kit uses a double antigen sandwich enzyme linked immunosorbent assay ELISA to analyze the existence or not of Chicken H5N1Ag in samples Add sample to wells pre coated with one Chicken Influenza A Virus Subtype HSN1 antibody at same time add HRP conjugated Chicken Influenza A Virus Subtype H5N1 antibody to bind the analyte followed by incubation and washing procedures to remove unbound substance Finally HRP substrates are added incubated for detection and a blue color is developed Reaction is stopped and color turns to yellow when Stopping Solution acidic is added The existence or not of Chicken HSN1Ag in the samples is then determined by comparing the O D of the samples to the CUT OFF 3 SAMPLE COLLECTION AND STORAGES Serum Use a serum separator tube and allow samples to clot for 2 hours at room temperature or overnight at 4 C before centrifugation for 20 minutes at approximately 2000xg Remove serum and assay
