特異性Specific to CD8. 14 can be used for: the detection of immunoregulatory T cell subset imbalances in autoimmune disorders and immunodeficiency states, categorisation of T cell acute lymphoblastic leukaemia and lymphoblastic lymphoma in conjunction with other antigens and determination of T4/T8 ratios in immune deficiencies, rheumatoid arthritis, multiple sclerosis, etc.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration.
1/60. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol. PubMed: 24594640
機能Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. CD8 alpha chains binds to class I MHC molecules alpha-3 domains.
関連疾患Defects in CD8A are a cause of familial CD8 deficiency (CD8 deficiency) [MIM:608957]. Familial CD8 deficiency is a novel autosomal recessive immunologic defect characterized by absence of CD8+ cells, leading to recurrent bacterial infections.
製品の状態CD8 beta tissue specificity: Isoform 1, isoform 3, isoform 5, isoform 6, isoform 7 and isoform 8 are expressed in both thymus and peripheral CD8+ T-cells. Expression of isoform 1 is higher in thymus CD8+ T-cells than in peripheral CD8+ T-cells. Expression of isoform 6 is higher in peripheral CD8+ T-cells than in thymus CD8+ T-cells.
CD8 beta PTM: Phosphorylated as a consequence of T-cell activation.
