Product Specific Information
Specificity: Clone 37.51 recognizes an epitope on mouse CD28.
Endotoxin Level: <0.5 EU/mg as determined by the LAL method. Purity: >95% by SDS Page; ≥98% monomer by analytical SEC.
Product Preparation: Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates. Pathogen Testing: To protect mouse colonies from infection by pathogens and to assure that experimental preclinical data is not affected by such pathogens, all of Leinco Purified Functional PLATINUM™ antibodies are tested and guaranteed to be negative for all pathogens in the IDEXX IMPACT I Mouse Profile.
Storage and Handling: Functional grade preclinical antibodies may be stored sterile as received at 2-8 C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80 C. Avoid Repeated Freeze Thaw Cycles.
This antibody has been tested in the following applications: Western Blotting, Immunoprecipitation, Functional Assay, CyTOF® Costimulation, Blocking.
Target Information
CD28 antigen is a 44 kDa disulfide linked homodimeric T cell specific surface glycoprotein. CD28 is a cell adhesion molecule of the immunoglobulin superfamily which is constitutively expressed on most peripheral blood T lymphocytes. Moreover, CD28 is the critical T cell costimulatory receptor that provides the cell the important second activation signal by binding CD80 and CD86 which are expressed by antigen presenting cells. In addition to its co-stimulation role, CD28 functions by preventing T cells from entering an anergic-hyporesponsive state or from undergoing premature apoptotic cell death. In murine peripheral lymphoid organs and in the blood, all CD4+ and CD8+ T cells express CD28. In the thymus, CD28 expression is highest on immature CD3-, CD8+ and CD4+8+ cells, and on CD4-8- cells that express alpha/beta and gamma/delta TCR. The level of CD28 on mature CD4+ and CD8+ alpha/beta TCR+ thymocytes is two- to fourfold lower than on the immature cells. Diseases associated with CD28 dysfunction include mycosis fungiodes and Sezary's Disease.
