  • Product overview

    Abcam’s CCL27 in vitro SimpleStep ELISA™ (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of CCL27 protein in Human serum, plasma and cell culture supernatants.

     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 substrate 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.

    Sensitivity: Samples diluted in Sample Dilunet NS - 9 pg/mL

                        Samples diluted in Sample Diluent 25BS - 19 pg/mL

  • Notes

    CC chemokine ligand 27 (CCL27) is a member of a superfamily of small secreted proteins that attract circulating lymphocytes to an area of injury/infection by binding with G protein-coupled receptors expressed on the migrating target cells. CCL27 is expressed in the skin and selectively attracts CLA+ memory T-cells into the skin microenvironment. CCL27 expression can be up-regulated by the proinflammatory cytokines TNF-α and IL-1β increasing migration of memory T-cells to the skin during inflammation. In normal skin suprabasal keratinocytes express minute amounts of CCL27; where as in lesions of human Atopic Dermatitis, Contact Dermatitis, and psoriasis, the keratinocytes demonstrate stronger expression of CCL27 which is thought to attract pro-inflammatory CLA+ memory T-cells to the lesions contributing to the inflammatory process and perpetuates the disease.

Our Abpromise guarantee covers the use of ab200013 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.

  • Background-subtracted data values (mean +/- SD, n = 2) are graphed.

  • Background subtracted data from duplicate measurements are plotted. Serum samples from a total of 10 individual Normal serum donors and 3 donors diagnosed with Atopic Dermatitis (AD) were assayed. Complete medical histories for all donors is not known.
