Elisa Kits
(BE102A)- HBsAb |
Hepatitis B is an infectious illness caused by hepatitis B virus (HBV) which is an envelope, 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 antigen (HBeAg)/HBeAb. As it is difficult to detect the core antigen in the serum, the other five are been done to diagnosing HBV. Hepatitis B “core” antigen (HBcAg) is a major component of the viral structure. Antibodies to HBcAg (anti-HBc total antibody, and IgM) appear shortly after the appearance of HBsAg and persist for life both in persons who have recovered from a hepatitis B infection and in those who develop HBsAg-carrier status but in rare cases, a HBV infection can also run its course without the appearance of immunologically detectable anti-HBc (usually in immunosuppressed patients). Anti-HBc is a marker of acute, chronic or resolved HBV infection and screening for anti-HBc provides with information on the prevalence of the disease in different groups. In the absence of other hepatitis B markers (HBsAg-negative persons), anti-HBc may be the only indication of an existing hepatitis B viral infection.

(BE103A)- HBeAg |
The Hepatitis B e antigen is found to be related to Hepatitis B viral infection. HBeAg is usually found in the early phase of Hepatitis B viral infection. The titer of HBeAg rises rapidly during the period of virus replication. The presence of HBeAg correlates with increasing numbers of infectious viruses (Dane particles) and the presence of viral specific DNA polymerase in serum. During the HBeAg positive stage, hepatitis B patients are at increasing risk of transmitting the virus to their contacts. Persistent presence of HBeAg in the hepatitis B virus carrier is often associated with chronic active hepatitis. More info: (BE103A)- HBeAg Quantity: 96 tests/kit x 5 Price: 246€

(BE104A)- HBeAb |
The presence of antibody against hepatitis B viral e antigen is used as an indicator for (1) early HBs antigenemia before the peak of viral replication and (2) early convalescence when HBeAg has declined below detectable levels. It is also useful to confirm a seroconversion. The seroconversion from HBeAg positivity to anti-HBe positivity indicates a reduced level of infectious virus because virus replication has decreased.

(BE301A)- HAV IgM |
This kit uses capture ELISA method to detect anti-HAV IgM. The purified mouse anti-human IgM (μchain) antibody is coated on the solid phase of multi-wells. A conjugate HAV-Ag is added to the coated wells after diluted sample added and incubated. Then horseradish peroxides labeled HAV-Ag is added. If HAV-IgM is present in the sample, a complex of Anti-μ-chain-HAV-IgM –HAV-Ag -labeled with HRP will form. Wash wells to remove other unbounded serum components, incubate with substrate (TMB) to form a colored product, and measure the absorbance at 450nm to indicate the presence or absence of HAV-IgM in the sample. The test is special, sensitive, reproducible and easy to operate.

(BE401A)- HEV IgG |
This kit employs solid phase, indirect ELISA method for detection of IgG antibodies to HEV (anti-HEV) in serum or plasma with two-step incubation procedure. Polystyrene micros well are pre-coated with purified activated recombinant HEV antigen. The HRP conjugated mouse anti human IgG (r chain) monoclonal antibody serves as tracer. TMB is substrate for HRP. The enzyme reaction with substrate TMB produces a color change, and the intensity of the absorbance at 450 nm indicates the presence or absence of Anti-HEV antibodies IgM in the sample. The test is specific, sensitive, reproducible and easy to operate. It is for blood screen of HEV infection. More info: (BE401A)- HEV IgG Quantity: 96 tests/kit x 5 Price: 252€ |

(BE501A)- EBV IgA |
Epstein-Barr virus, frequently referred to as EBV, is a member of the herpes virus family and one of the most common human viruses. The virus occurs worldwide, and most people become infected with EBV sometime during their lives. In developed countries, 80 - 90% of the adult population has been infected by the virus.

(BE601A)- Anti-HIV 1&2 |
Human Immunodeficiency Virus Type (HIV-1) has been isolated from patients with AIDS and AIDS-related complex (ARC). HIV-1 was thought to be the sole causive agent of these syndromes until 1986, when a second type of Human Immunodeficiency Virus (HIV-2) was isolated and also reported to cause AIDS. Since the initial discovery, more than 600 cases of HIV-2 infection have been documented worldwide, with over 40 cases of AIDS related to HIV-2.
