Hepatitis B is an infectious illness caused by hepatitis B virus
(HBV) which is an enveloped, double-stranded DNA virus belonging to
the Hepadnaviridae family and is recognized as the major cause of
blood transmitted hepatitis together with hepatitis C virus (HCV).
HBV is excreted in body fluids such as semen, saliva, blood and
urine in persons with acute or chronic infection. The hepatitis B
virus is known as a blood-borne virus because it is transmitted
from one person to another via blood or fluids contaminated with
blood. Transmission of hepatitis B virus results from exposure to
infectious blood or body fluids.When HBV invades the body it causes
liver damage through induction of auto-immunity.
Three immunity has been found, surface antigen (HBsAg)/HBsAb, core
antigen (HBcAg)/HBcAb and e antigen(HBeAg)/HBeAb. As it is
difficult to detect the core antigen in the serum, the other five
are been done to diagnosing HBV.
2. MATERIALS PROVIDED
1. Microplate 1 block (96wells) 2. Negative Control 1 ml ×1 3. Positive Control 1 ml ×1 4. Conjugate 6 ml ×1 5. Substrate Solution A 6 ml ×1 6. Substrate Solution B 6 ml ×1 7. 20×Wash Buffer 40 ml ×1 8. Stop Solution 6 ml ×1 9. Plate Cover 3 piece 10. Insert 1 copy
3. TEST PROCEDURE
Dilute samples: Use the Normal Saline(0.9% NaCl) to dilute the samples(The
samples must be diluted 1:999 before use.). The Positive Control
and Negative Control have no use for dilution.
Add samples:Open the foil pouch and remove the microplate. Dispensing 50μl of
diluted samples , Positive Control and Negative Control to each
well except the blank well. Gently vibrating the microplate. Cover
and incubate for 30 minutes at 37℃.
Wash the plate:Dilute 1 volume of wash buffer concentrate with 19 volumes of
distilled water, mix well. Remove the solutions from all the wells.
Fill the wells with the diluted wash solution (at least 20 seconds
to soak) then remove the diluted wash buffer from the wells. Repeat
the procedure for 5 times. Make sure that the rest volume is
minimal, by blotting dry by tapping plate onto absorbent paper.
Add conjugate:Add the 50μl of conjugate to each well (except the blank well).
Cover and incubate for 30 minutes at 37℃.
Wash the plate:Repeat the wash procedure as in step 2.
Add 50μl of Substrate Solution A and 50μl of Substrate Solution B
to each well, mix well. Cover and incubate for 10 minutes at 37℃.
Stop reaction:Add 50μl stop solution to each well, mix well.
Read the absorbance at 450 nm. If a dual wavelength measurement is
used, the reference wavelength should be selected from 620nm to
690nm.
