Cathepsin G Antibody ELISA Kit

  • Created on the 31 May, 2017.


Human cathepsin G ELISA kit can be used for detecting in vitro quantitative amounts of IgG auto-antibodies to cathepsin G (CTSG) antibody in human serum and plasma. This assay has a minimum analytical sensitivity limit of 0.5 U/ml.


Cathepsin G (CTSG) is a member of the cathepsins family of intracellular proteases which are mainly located in the liver, kidney and the spleen. It plays major roles in the elimination of intracellular pathogens, breakdown of tissues at inflammatory sites and triggering anti-inflammatory responses. Cathepsin G is a 255 amino acids protein which consists of a two residue N-terminal activation peptides, an 18-residue signal peptide and a carboxy terminal extension. The activity of the protein is dependent on the catalytic triad that is made up of aspartate, histidine and serine residues. These generally tend to close together near the active site of the enzyme when in the tertiary structure. Other functions of cathepsin G include platelet activation, induction of airway submucosal gland secretion, cleavage of receptors, conversion of angiotensin to angiotensin II and blood-brain barrier breakdown. It has been reported to play vital roles in a number of different diseases such as coronary artery disease, ischemic reperfusion injury, rheumatoid arthritis, bone metastasis and periodontitis. Cathepsin G ELISA kit is an ideal to tool for many diagnostic applications.


The minimum detection sensitivity level of IgG antibodies to human cathepsin G (CTSG IgG) using this human cathepsin G ELISA kit was 0.5 U/ml. The dynamic assay range for this kit is 6.3 – 100.0 U/ml.

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.
