A Proliferation Inducing Ligand (APRIL) ELISA Kit

  • Created on the 1 April, 2017.


Human APRIL ELISA kit is designed for detecting in vitro quantitative concentrations of a proliferation-inducing ligand (APRIL) in human serum, plasma, tissue homogenates, cell lysates, cell culture supernatant and other biological fluids. This assay has a minimum sensitivity limit of < 2.45 ng/ml.


A proliferation-inducing ligand (APRIL) can also be called tumor necrosis factor ligand superfamily member 13 (TNFSF13) and it is a protein belonging to the TNF superfamily which is able to be recognised by the cell surface receptor TACI. APRIL is designed CD256 when using the cluster of differentiation terminology. It is known to display low levels of expression in normal cells and high levels of expression in tumors from different origins. In particular it shares two TNF receptor family members, BCMA and TACI with another TNF homolog, BlyS/BAFF, both of these have been reported to play essential functions in cancer and autoimmune disease.

APRIL has a major role in T cell survival and T-independent type II antigen responses, however it is also able to induce the survival or proliferation of non-lymphoid cells. Biologically active APRIL and BlyS/BAFF heterotrimers have been identified to be expressed in patients with systemic immune-based rheumatic diseases. Also, local production of APRIL is discovered in arthritic joints of patients with inflammatory arthritis. There are evidence that a soluble form of the high affinity BCMA receptor has the ability to inhibit the proliferative activity of APRIL in vitro, this leads to reducing the tumor cell proliferation. Whereas, APRIL-transfected cells are found to display an increased rate of tumor growth directly, this observation indicates that APRIL could be implicated in the regulation of tumor cell growth. The following APRIL ELISA kit is ideal for various diagnostic applications.


The minimum detection sensitivity level of a proliferation-inducing ligand using current human APRIL ELISA kit was 2.45 ng/ml. The dynamic range for this assay is 5.0 – 2,000.0 ng/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.
