It uses our proprietary SimpleStep ELISA® technology. Quantitate Rat OX40 with 53 pg\/ml sensitivity.\u003cbr\u003e\nSimpleStep 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:\u003cbr\u003e\n- Single-wash protocol reduces assay time to 90 minutes or less\u003cbr\u003e\n- High sensitivity, specificity and reproducibility from superior antibodies\u003cbr\u003e\n- Fully validated in biological samples\u003cbr\u003e\n- 96-wells plate breakable into 12 x 8 wells strips\u003cbr\u003e\nA 384-well SimpleStep ELISA® microplate (\u003cbr\u003e\nab203359\u003cbr\u003e\n) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.\u003cbr\u003e\nOX40, also known as TNFRSF4 and\/or CD134, is a constitutively expressed transmembrane receptor found on T-cells. OX40 serves as a secondary checkpoint for immunological responses through the binding of TNF receptor associated factor (TRAF) proteins. OX40 and its predominant ligand, OX40L, regulate adaptive T cell immune responses. Clinically, OX40 is the target of several immunotherapy antibody treatments to promote antitumor immunity.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nCD134 also known as OX40 or TNFRSF4 is a receptor that plays an essential role in immune response regulation. This receptor is part of the tumor necrosis factor receptor (TNFR) superfamily and has a molecular mass of approximately 50 kDa. CD134 is expressed on activated T cells particularly CD4+ T cells and is present on various other immune cells under specific conditions. The receptor binds to the OX40L its ligand which is expressed on antigen-presenting cells such as dendritic cells and B cells.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nCD134 influences T cell proliferation survival and memory formation being an important component of the immune system's adaptive response. OX40L engagement with CD134 enhances the activation and survival of T cells promoting long-term immunity. This interaction does not form part of a larger complex but functions as a direct signaling mechanism that augments T cell receptor (TCR) signaling leading to increased cytokine production and sustained immune responses essential for controlling infections and cancer.\u003cbr\u003e\nPathways\u003cbr\u003e\nCD134 signaling intersects with the nuclear factor-kappa B (NF-κB) and phosphoinositide 3-kinase (PI3K) pathways. These pathways play significant roles in regulating immune responses and cell survival. Through the NF-κB pathway CD134 influences gene transcription related to immune activation. It also connects with other immune regulatory proteins such as CD28 which further potentiates T cell responses and enhances effector functions.\u003cbr\u003e\nCD134 has connections to autoimmune diseases and cancers. Overactivity of the CD134-OX40L pathway can lead to exacerbated autoimmune conditions such as lupus. This receptor has also been implicated in tumor immunity where its activation enhances the anti-tumor response of T cells. CD134 interacts with CTLA-4 another immune checkpoint protein playing a role in balancing immune activation and regulation within these disease contexts.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843594735785,"sku":"ab255725","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab255725","provider":"Iright","version":"1.0","type":"link"}
