  • Product overview

    4-1BBL in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of 4-1BBL protein in human serum, plasma (citrate) and cell culture supernatant.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB Development Solution is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

    4-1BBL is a cytokine normally found on antigen presenting cells and is part of the TNF superfamily. When bound alongside with 4-1BB, a type 2 transmembrane glycoprotein receptor, its joint pathway provides the T-lymphocytes with costimulatory signals for proliferation, differentiation, and survival. 4-1BBL is a well-known target for anticancer immunotherapy.

  • Research areas

  • Function

    Cytokine that binds to TNFRSF9. Induces the proliferation of activated peripheral blood T-cells. May have a role in activation-induced cell death (AICD). May play a role in cognate interactions between T-cells and B-cells/macrophages.
  • Tissue specificity

    Expressed in brain, placenta, lung, skeletal muscle and kidney.
  • Sequence similarities

    Belongs to the tumor necrosis factor family.

Our Abpromise guarantee covers the use of ab246536 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Sandwich ELISA Use at an assay dependent concentration.


  • SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.


  • The 4-1BBL standard curve was prepared as described in Section 10. Raw data values are shown in the table. Background-subtracted data values (mean +/- SD) are graphed.

  • The concentrations of 4-1BBL were measured in duplicates, interpolated from the 4-1BBL standard curves and corrected for sample dilution. Undiluted samples are as follows: Raji (PMA treated) cell culture supernatant 50% and Raji (untreated) cell culture supernatant 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean 4-1BBL concentration was determined to be 143.7 pg/mL in Raji (PMA treated) cell culture supernatant, and 59.2 pg/mL in Raji (untreated) cell culture supernatant.
