Quality Control: As GMP-certified products, every batch is nationally quality guaranteed
Polystyrene microtiter strip wells have been coated with antigen. The test sample is incubated in such a well; antibodies specific for HIV-1 and HIV-2, if present in the sample, will bind to the antigen fixed onto the microplate wells. The wells are washed to remove unbound components and the antigen labeled with horseradish peroxidase are added to the wells. The enzyme conjugates will bind to the antigen-antibody complex and excess unbound enzyme conjugates are removed by washing again. Incubation with enzyme substrate produces a blue
color in the microwelll, which turns yellow when the reaction is stopped with sulphuric acid. If the sample contains no HIV-1 and/or HIV-2 specific antibodies, the labeled antibody cannot be bound specifically and only a low background color develops.

Automatic Operation Instrument: Fully automatic enzyme immunoassay analyzer
Manual Operation Instrument:
- 37 ºC thermostat or water bath
- Micropore oscillator
- Micropipette 25 μl -200 μl
- Microplate reader: detection wavelength 450nm, reference wavelength 630nm
- Microplate washer or bottle washer
1. This immunoassay kit is an in vitro diagnostic for the detection of HIV-1 and/or HIV-2 in Human serum or plasma.
2. Human serum and plasma should be stored at temperature of 2 to 8ºC.
For long term storage, both human serum and plasma should be stored at temperature of -20ºC, avoid repeated freeze-thaw.
1. Dilute the concentrated wash solution 1:25 with purified water. ( For example: 480ml purified water add with 20ml wash solution fully blended to get 500ml working concentration detergent for use.)
2. Open the aluminum bag and take out the microplate with the required number of strips.
3. Set 2 wells for Anti-HIV-1 positive control (100ul per well), 1 well for Anti-HIV-2 positive control ( 100ul per well), 1 well for Anti-HIV negative control (100ul per well), 1 well for blank control ( Not to add sample and conjugate into blank control well but add only zymolyte and stopping solution) per experiment. Pipette 100ul of sample for testing into rest wells.
4. Cover the microplate with a plate sealer. Incubate at 37ºC for 60 minutes.
5. Take out microplate and tear plate sealer, wash each well with wash solutions for 5 times. If washing manually, discard liquid in wells, fill in each well with concentration wash solution mentioned in Step 1 and keep for 30 - 60 seconds with concentration wash solution into each well before spin-dry. After 5 times repeating, pat dry microplates on clean absorbent tissues. If washing by microplate washer, select 5 times' washing procedure, fill in each well with concentration wash solution mentioned in Step 1 and keep for 30 - 60 seconds with concentration wash solution into each well, each well should be absorbed completely, without any residual. Pat dry microplates on clean absorbent tissues after washing.
6. Pipette 100ul of conjugate into the well that contained specimen, positive control and negative control. Cover the microplate with a plate sealer after mixing uniformity. Incubate at 37ºC for 30 minutes.
7. Repeat the procedure 7.
