ENA-6 Profile ELISA Kit

  • Created on the 2 June, 2017.


Extractable nuclear antigen (ENA-6) are intending for profiling one or more autoantibodies that has the ability to react with proteins within the cell nucleus. These are vital in helping to diagnose autoimmune disorder and aiding in distinguishing between different disorders, this is possible because one or more anti-ENA antibodies are found to be associated to specific autoimmune disorders. The ENA profile assay can be either an ENA-4 or an ENA-6 autoantibody tests. The 6-test ENA profile will include anti-Sm, anti-SS-A (Ro), anti-SS-B (La), anti-RNP, Scl-70 and Anti-Jo-1.


Human ENA-6 ELISA kit is a procedure for profile screening in-vitro quantitative levels of IgG autoantibodies to extractable nuclear antigens (ENAs) in human serum and plasma samples. This assay has a minimum analytical sensitivity limit of diagn. 86.4%.

Extractable nuclear antigens Sm, RNP/Sm, Jo-1, SS-A (52 and 60 kDa), SS-B and Scl-70 are bound to the microwells.


The minimum detection sensitivity level of human extractable nuclear antigen profile (ENA-6 profile) using this human ENA-6 ELISA kit was diagn. 86.4%. The dynamic assay range for this kit is to a cut-off index 1.0.

Your secretory IgA ELISA kit 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 kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits 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 kits. You have such an easy and simple system, yet it is very effective.
