FeLV-gp27 ELISA Kit (Feline Leukemia Virus)
Full Name: FeLV-gp27 ELISA Kit (Feline Leukemia Virus)
Reactivity: Feline
Sample Type: Serum, Plasma
Sensitivity: Qualitative
BACKGROUND
Feline leukemia virus (FeLV) is responsible for causing various blood disorder such as leukaemia and lymphoma in cats. If the virus is not defeated by the animal’s immune system then this could lead diseases which might be lethal. FeLV-A is a retrovirus with an RNA genome, meaning it is passed to offspring by the mother and can be passed on to other cats through contact with infected saliva or blood. It causes about 50% of all cases of feline leukaemia. Infection with FeLV-A is more likely to be congenital (occurring in the womb). In this case, the retrovirus was transmitted to the embryo and has persisted for generations in susceptible cats. No one knows how FeLV-A spreads from cat to cat. Feline leukemia virus Type A causes a disease called feline leukaemia or feline AIDS. Feline leukaemia is an often fatal cancer of white blood cells that attacks bone marrow, lymph nodes and spleen, leaving affected cats extremely vulnerable without treatment. Other causes may include chromosomal abnormalities, radiation exposure or some types of cancer treatment. Signs appear as anemia and weight loss, with blood tests indicating leukemia cells in the bone marrow and in lymph nodes.
One of the major core protein of FeLV is FeLV p27-antigen, this antigen can be found in the blood of infected felines. The following assay offers an alternative to the more widely used method IFA test on blood smears, with both procedures providing comparable results. We would also recommend carrying out an IFA, PCR or virus-isolation in order to confirm a positive ELISA result.

ASSAY CHARACTERISTICS
– FeLV postive control should give an OD (450nm) ≥ 1.000.
– Negative control must be lower OD (450nm) than 0.400.
– A sample is considered positive when the measured extinction is higher than 3 times the OD of the negative control.
