Product details:
Human CD70 ELISA Kit (ab264621) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of CD70 protein in cell lysate and cell culture extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human CD70 with 0.1 ng/ml sensitivity.
SimpleStep ELISA® technology 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. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
CD70 is a cytokine which acts as a ligand to CD27. The binding of CD70 to CD27 induces the proliferation of co-stimulated T-cells and enhances cytolytic T-cell generation. CD70-CD27 pathway plays an important role in the generation and maintenance of T-cell immunity during antiviral response.

CD70 also known as CD27 ligand or CD27L is a type II transmembrane protein with a molecular mass of approximately 30 kDa. It belongs to the tumor necrosis factor (TNF) superfamily and is encoded by the CD70 gene. The expression of CD70 occurs mainly on activated T and B cells dendritic cells and some NK cells but not on resting lymphocytes. In addition CD70 expression is observed in certain malignancies and inflammatory conditions.
Biological function summary
CD70 plays an essential role in the regulation of immune responses. It does this by binding to its receptor CD27 forming a receptor-ligand complex that triggers signaling pathways vital for T cell proliferation survival and differentiation. This interaction also influences the production of immunoglobulins by B cells. CD70-CD27 signaling is particularly important in shaping adaptive immunity enhancing the body's ability to respond to pathogens effectively.
Pathways
CD70 is integral in the activation of the NF-κB and MAPK pathways. These pathways are activated upon the interaction of CD70 with CD27 promoting cell survival proliferation and pro-inflammatory cytokine production. Other proteins related to CD70 through these pathways include TRAF2 and TRAF3 which are essential for downstream signaling events that modulate immune responses.
CD70 has been implicated in autoimmune diseases and certain cancers. For instance it plays a role in the pathogenesis of lupus by contributing to abnormal immune activation. Overexpression of CD70 is also associated with various cancers such as renal cell carcinoma where it can support tumor cell growth and immune evasion. Through these conditions CD70 interacts with proteins like BCL-2 in cancer affecting cell survival pathways while its interaction with CD27 influences the immune deregulation seen in lupus.
