FCV (Feline Calici Virus) ELISA Kit (Feline)


Feline calici virus ELISA kit can be used for measuring antibodies against feline calici virus (FCV or feline calicivirus) in samples of serum or plasma. This assay has a quantitative and qualitative standard range.


Feline calicivirus (FCV) infection is a major cause of upper respiratory infections, which is more commonly known as cat flu. The virus is able to attack the respiratory tract, lungs, nasal passage and the mouth. It can also cause ulceration of the tongue, intestines and the musculoskeletal system. This is a ubiquitous virus and is responsible for causing the disease in cats throughout the world. At present there have been at least 40 different strains of FCV that have been discovered and the severity or the virulence of the disease resulting from the different strains can vary considerably. Even though vaccination against calicivirus is highly recommended, it seems to have failed in decreasing the prevalence of the disease. Some of the important things to consider during the diagnosis step include: clinical history, clinical signs, eye examination and laboratory findings. Method such as PCR and immunohistochemical staining have been useful in diagnosing this disease.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

The standard range of antibodies to feline calicivirus (FCV) using current feline calici virus (FCV) ELISA kit is qualitative and quantitative. Please contact us for the protocol insert for more details.


– Feline Calici Virus (FCV): ELISA
– Weak positive control should give an extinction ≥ 1.500 OD and an endpoint titer ≥ 90.
– Negative control should give an OD ≤ 0.600 and an endpoint titer =< 30.
– A titer ≥ 270 is considered to be protective, under normal virus pressure.
– Summary:
(i). < 30 = no antibodies found.
(ii). > 90 = antibodies found, retest in 3 months. (probably shedding FCV)
(iii). > 270 = high titer, considered to be protective.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
