Scl-70 Ab ELISA Kit

  • Created on the 29 June, 2017.


Human anti-Scl-70 ELISA kit is designed for determining in-vitro quantitative concentrations of IgG auto-antibodies to topoisomerase 1 (topo-1, Scl-70, anti-Scl-70) in human plasma and serum. This assay has a minimum analytical sensitivity limit of 1.0 U/ml.


Topoisomerase 1 (also called Scl-70) is a nucleolar and nuclear enzyme which is regarded as being specific for systemic sclerosis (scleroderma) and it can be found in over 60% of patients possessing this connective tissue disease. Scleroderma has been associated with a number of autoantibodies, each of which can be helpful in diagnosing the affected patients and in determining the prognosis. Anti-Scl-70 and anti-centromere antibodies (ACA) are particularly useful in distinguishing patients having systemic sclerosis (SSc), these antibodies are associated with more severe scleroderma disease. The following anti-Scl-70 ELISA kit is ideal for various diagnostic applications.


The minimum detection sensitivity level of anti-topoisomerase 1 (topo-1, anti-Scl-70, Scl-70) IgG autoantibodies using current human anti-Scl-70 ELISA kit was 1.0 U/ml. The dynamic range for this assay is 12.5 – 200.0 U/ml.

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.
