By determining phosphorylated Syk protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blotting analysis.\u003cbr\u003e\nThis Sandwich ELISA kit is an\u003cbr\u003e\nin vitro\u003cbr\u003e\nenzyme-linked immunosorbent assay for the measurement of human phospho-Syk. An anti-Syk antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and phosphorylated and unphosphorylated Syk present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated antiphosphotyrosine antibody is used to detect only tyrosine-phosphorylated protein. After washing away unbound antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of phospho-Syk bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.\u003cbr\u003e\nREACH authorisation\u003cbr\u003e\nAbcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.\u003cbr\u003e\nIt is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions--20°C, Appropriate long-term storage conditions--20°C, Storage information--20°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nSpleen tyrosine kinase commonly known as Syk is a non-receptor tyrosine kinase with a mass of about 72 kDa. It serves as a critical signaling molecule in immune cells. Syk is expressed in various cell types such as B cells T cells monocytes and others involved in the immune response. It initiates signaling cascades by binding to immunoreceptor tyrosine-based activation motifs (ITAMs). Alternate forms include phosphorylated Syk often referred to as p-Syk which activates various downstream signaling pathways.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nSyk plays a role in transmitting signals from the cell surface to the interior of the cell facilitating various cellular activities. It is a part of signal transduction complexes and functions in the regulation of immune cell activation differentiation and survival. It affects processes like Fc receptor signaling in macrophages and neutrophils impacting immune responses and inflammation. The phospho-Syk form influences the strength and duration of signaling affecting various cellular functions.\u003cbr\u003e\nPathways\u003cbr\u003e\nSyk is significant in the B-cell receptor (BCR) signaling pathway and Fc receptor signaling pathway. Within these pathways Syk interacts with proteins like Lyn and Fyn which are other kinases involved in BCR signal transduction. Syk phosphorylation noted as p-Syk plays a part in activating downstream molecules such as phospholipase C gamma (PLCγ) to mediate cellular responses to external stimuli. The critical role of Syk in these pathways influences both adaptive and innate immune responses.\u003cbr\u003e\nSyk correlates with conditions like rheumatoid arthritis and certain B-cell lymphomas. In rheumatoid arthritis aberrant Syk signaling contributes to the inflammation and joint destruction characteristic of the disease. Syk's role in B-cell antigen receptor signaling links it to B-cell lymphomas where dysregulation in signaling pathways leads to uncontrolled proliferation of malignant B cells. The involvement of Syk in both disease contexts suggests its potential as a therapeutic target along with pathways related to proteins like BLNK and PLCγ in these disorders.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46855644020905,"sku":"ab279949","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab279949","provider":"Iright","version":"1.0","type":"link"}
