Histone Ab ELISA Kit

  • Created on the 12 June, 2017.

INTENDED USE

Human anti-histone ELISA kit is a method for measuring in-vitro quantitative amounts of IgG auto-antibodies to histone antibody (anti-histone-IgG) in human serum or plasma. This assay has a minimum analytical sensitivity limit of 1.0 U/ml.

BACKGROUND

Histones auto-antibodies are highly conserved in many species and are the major basic protein that is found in chromatin. There are essentially 5 different classes of histone (H1, H2, H2b, H3 and H4), ranging in molecular weight from 11-23 kD and all containing the arginine and lysine basic amino acids. Histone auto-antibodies are a type of antinuclear antibodies (ANA) which are known to be associated to many different autoimmune diseases such as lupus. The presence or even an absence of a particular antinuclear antibodies can be a useful aid in determining a specific disorder. There is evidence that drugs can be used to stimulate the production of histone antibodies but there is also a possibility that this can lead to a type of lupus (drug-induced lupus erythematosus). Many drugs have been associated with drug-induced lupus in some people such as hydralazine, penicillamine, isoniazid, quinidine, procainamide and minocycline. However, majority of anti-histone antibodies in drug induced lupus erythematosus are of temporary character and tend to disappear within a few months after treatment. The following anti-histone ELISA kit is designed to be used for many diagnostic applications.

SENSITIVITY

The minimum detection sensitivity level of histone IgG auto-antibodies (anti-histone-IgG) using current human anti-histone ELISA kit was 1.0 U/ml. The dynamic range for this assay is 12.5 – 200.0 U/ml.

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.
