HBeAg ELISA Kit
HBeAg ELISA Kit (乙肝E抗原HBeAg检测试剂盒) is a one-step, qualitative , enzyme-linked immunosorbent assay (ELISA) test kit, based on the Double Antibody Sandwich ELISA principle, which is used to detect Hepatitis-B E-antigen in human Serum or Plasma specimen.
Please refer to the Instruction for Use (IFU) of the HBeAg ELISA Kit.
(IFUs are subject to changes without prenotice; reading the package insert before carrying out any assay, it is always a good protocol for laboratory activity.)

To carry out the assay with a HBeAg ELISA Kit, Serum or Plasma should be collected according to the instructions given in the Instruction For Use included in the test kit. After collecting, it is preferable to perform the testing as early as possible; if not viable, the specimen should be stored properly. A general introduction about the collection, and storage of the specimens is given below.
Collect blood specimen into a lavender, blue or green top blood collection tube, containing EDTA, citrate or heparin, respectively, by vein puncture.
Separate the plasma by centrifugation.
Carefully withdraw the plasma into a new pre-labeled tube.
Collect blood specimen into a red top blood collection tube by vein puncture, which contains no anticoagulants.
Allow the blood to clot, or separate the serum by centrifugation.
Carefully withdraw the serum into a new pre-labeled tube.
Serum, Plasma Storage Condition
Test specimens as soon as possible after collecting. The specimens can be stored up to 3 days at 2-8°C if not tested immediately. The specimens should be frozen at -20°C for longer time storage. Don’t freeze and thaw the specimens for many times. Prior to testing, bring frozen specimens to room temperature slowly and mix gently. Specimens containing visible particulate matter should be clarified by centrifugation before testing. Do not use samples demonstrating gross lipemia, gross hemolysis or turbidity in order to avoid interference on result interpretation.
Double Antibody Sandwich ELISA method is used in this HBeAg ELISA Kit to detect the Hepatitis-B E-antigen in human Serum or Plasma specifically. The introduction of this Double Antibody Sandwich ELISA testing principle is given blow.
With this type of ELISA test kits, the detection target usually is hormone protein or viral antigen.
In the test kit, monoclonal or polyclonal antibodies specific to the target protein or antigen are used as capturer, which are pre-coated on the polystyrene microwell strips. The sample from the patient, such like urine, serum or plasma sample is added to the microwells. And a second antibody conjugated with horseradish peroxidase (HRP) is used as the detector, which then is added to the microwells. Usually, the samples and the second antibody conjugate are added to the microwell in the same time, thus it is a one-step assay process.
During incubation, the specific immuno-complex formed in case of presence of the target antigen or protein in the sample, and is captured on the solid phase.
After washing to remove sample serum proteins and unbound HRP-conjugate, Chromogen solutions containing tetramethyl benzidine (TMB) and urea peroxide are added to the wells. In presence of the antibody-antigen-antibody (HRP) "sandwich" immuno complex, the colorless Chromogens are hydrolyzed by the bounded HRP-conjugate to a blue colored product. The blue color turns yellow after stopping the reaction with sulfuric acid, indicating a positive result. The amount of color can be measured and is proportional to the amount of antigen or protein in the sample.
Wells containing samples negative for the target antigen or protein remain colorless.
