  • Product overview

    Abcam’s IL-15 (Interleukin-15) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human IL-15 in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for Human IL-15 coated on a 96-well plate. Standards and samples are pipetted into the wells and IL-15 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human IL-15 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of IL-15 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

    Get results in 90 minutes with Human IL-15 ELISA Kit (ab176110) from our SimpleStep ELISA® range.

    IL15 (114 amino acids) is a cytokine that regulates T and natural killer cell activation and proliferation. It has a predicted molecular mass of approximately 12.5 kDa. Human IL15 shares approximately 97% and 73% amino acid sequence identity with simian and mouse IL15, respectively. Both human and simian IL15 are active on mouse cells. IL15 was initially isolated from the simian kidney epithelial cell line CV1/EBNA. It has also been isolated from mouse and human cell sources. The cytokines IL15 and IL2 share many biological properties and stimulatory activities (T, B, and NK cells). Both IL15 and IL2 stimulate mouse CTLL2 cells. In activated peripheral blood T lymphocytes, IL2 is highly expressed but the expression of IL15 is not detectable. There is no sequence homology between IL15 and IL2, though computer modeling indicates both possess a four alpha helical bundle structure. IL15 competes for binding sites with IL2, as both IL2 and IL15 stimulate the growth of cells through the IL2 receptor. IL15 mRNA is expressed in many cell types and tissues including adherent peripheral blood mononuclear cells, fibroblasts, and epithelial cells, monocytes, placenta, and skeletal muscle.
  • Cellular localization

Customer reviews and Q&As

easy IL15 ELISA

Good Excellent 5/5 (Ease of Use)
IL15 was measured in human culture supernatants, diluted with assay diluent B as recommended.
Solid standard curve and very easy to use kit. However, according our ODs of the standards, the kit is not quite as sensitive as stated.

I am getting back to you in regards to the problems experienced when using this kit.

We have not yet encountered an issue with our ELISA kits that were caused by not printing the capture antibodies. All of our kits are pre-coated.

I appreciate your patience and apologize for keeping you waiting.

As none of the standards gave strong signal responses it could be that the standard recombinant protein has degraded. However, because th...

Since the protocol recommends to store the concentrateat 4°C for 5 days, this is what would be best. If the concentrate is still good after 21 days and how good it is, that would need to be tried out and is d...
