Product details

Human TSLP ELISA Kit ab192149 is a rapid single-wash 90-min Sandwich ELISA to measure Human TSLP in cell culture supernatant, serum. This SimpleStep sensitivity is 3 pg/mL.

How the assay works

Human TSLP SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.

Assay Specificity

Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Human TSLP ELISA Kit ab192149 protocol summary

1. Mix: add samples/standards to the wells together with the capture and detector antibody cocktail. Incubate 1 hr at room temperature
2. Wash
3. Add TMB development solution - incubate for 10 min
4. Add Stop solution
5. Read the results on a plate reader at 450 nm

Thymic stromal lyphopoietin (TSLP) is a protein belonging to the IL-7 cytokine family. TSLP is released by epithelial cells and keratinocytes in response to trauma, infection or allergen. It acts upon dendritic cells to mediate TH2 mediated immune response and appears to be a key mediator in many inflammatory diseases such as: Asthma, Eczema, and Atopic Dermatitis. TSLP also acts upon mast cells promote the release of IL-5, -6, and -13 in the presence of IL-1 and TNF-?.

Supplementary information

TSLP or thymic stromal lymphopoietin is a cytokine protein weighing around 27 kDa. It is also known as a hematopoietic cytokine and functions in the signaling processes of the immune system. TSLP is expressed in epithelial cells most notably in the skin lungs and gut. This cytokine holds significance due to its role in immune responses acting through its receptor complex made of TSLP receptor (TSLPR) and the interleukin-7 receptor alpha chain (IL-7R?).
Biological function summary

TSLP plays a role in mediating immune system responses. It induces the differentiation of T-helper 2 (Th2) cells promoting a specific type of immune response. TSLP does not appear to be part of a larger protein complex but it often functions in association with the TSLPR and IL-7R? receptor complex. It influences the activity and maturation of dendritic cells which are important for initiating immune responses.

Pathways

A mechanical understanding of TSLP reveals its involvement in both the JAK-STAT and NF-kB signaling pathways. It interacts with proteins like JAK2 and STAT5 which are important for the downstream signaling cascade leading to inflammation and immune responses. These pathways play important roles in the immune system's ability to detect and respond to environmental triggers.

TSLP has relevance in conditions like asthma and atopic dermatitis. It promotes inflammation that contributes to these allergic diseases. The dysregulation of TSLP expression can exacerbate these conditions. In asthma TSLP interacts with proteins such as interleukin-33 (IL-33) to enhance inflammatory responses in airway tissues. In atopic dermatitis connections with interleukin-4 (IL-4) are noted as both cytokines contribute to the inflammatory processes involved in the disease pathology. These associations make TSLP a potential target for therapeutic interventions in such disorders.
