Product Description

KHB Diagnostic Kit for Antibody to Treponema Pallidum (ELISA)
 
Product Description

KHB is the only supplier of rapid plasma reagents for Syphilis in China

Good Performance: Excellent clinical result in CDC report

Quality Control: As GMP-certified products, every batch is nationally quality guaranteed

 
Principle of the Assay

Polystyrene microtiter strip wells have been coated with the recombinant T. pallidum antigens (TP-47 KDa and other antigens) which constitutes the solid-phase antibody. The test sample is incubated in such a well; T. pallidumspecific antibodies, 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 antigens 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 reaction is stopped with sulphuric acid. If the sample contains no T. pallidum specific antibodies, the labeled antibody cannot be bound specifically and only a low background color develops.

Applicable Instrument

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

 
Specimen Requirement

1. This immunoassay kit is an in vitro diagnostic for the detection of Treponema Pallidum in Human serum or plasma.

2. Human serum and plasma should be stored at 2 to 8 ºC.
    For long term storage, both human serum and plasma should be stored at temperature at -20ºC, and avoid repeated freeze-thaw.
 

Operation Procedure

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. Pipette sample, negative control and positive control separately at volume of 100ul into each related reaction holes. (5 holes are suggested to be reserved as comparison hole. There are: 2 holes for negative comparison, 1 hole for positive control, 1 hole for chromogen blank comparison. User can adjust themselves as well.)

4. Cover the microplate with a plate sealer. Incubate at 37ºC for 60 minutes.

5. Take out microplate and tear plate sealer, wash each hole with wash solutions for 5 times. If washed manually, discard liquid in every holes, fill in each hole with concentration wash solution mentioned in Step 1 and keep for 30 - 60 seconds with concentration wash solution into each hole before spin-dry. After 5 times repeating, pat dry microplates on clean absorbent tissues. If washed by microplate washer, select 5 times' washing procedure, fill in each hole with concentration wash solution mentioned in Step 1 and keep for 30 - 60 seconds with concentration wash solution into every hole, every hole should be absorbed completely, without any residual. Pat dry microplates on clean absorbent tissues after washing.

6. Pipette 100ul of conjugate into those holes with specimen, positive control and negative control added.

7. Concussion for 10 seconds on microporous oscillator or gently concussion for 10 seconds manually.

8. Cover the microplate with a plate sealer. Incubate at 37ºC for 30 minutes.

9. Take out microplate and tear plate sealer, wash every hole with wash solutions for 5 times. The washing procedure is same as the procedure mentioned in Step 5.

10. Pipette 50ul of Chromogen A and 50ul of Chromogen B into every hole, blend to get uniformity. 

11. Concussion for 10 seconds on microporous oscillator or gently concussion for 10 seconds manually.

12. Cover the microplate with a plate sealer. Incubate at 37ºCfor 30 minutes.

13. Fill in every hole with 50ul stopping solution, Shake the microplate for 5 seconds to get blending uniformity completely. 

14. Use microplate reader to read and select wavelength at 450nm. (Recommendation to use dual wavelength microplate reader to colorimetric, reference wavelength 630nm or close to wavelength at 630nm.) If need to deduct chromogen blank, the chromogen blank control well needs to be zero correction firstly before reading OD value of each well.
