                描述Recombinant Mouse CD28 is produced by our Mammalian expression system and the target gene encoding Asn20-Lys149 is expressed with a Fc, 6His tag at the C-terminus.
                别名T-cell-specific surface glycoprotein CD28,CD28
                形?/td>Lyophilized from a 0.2 μm filtered solution of 20mM PB,150mM NaCl,pH7.4.
                来源Human Cells
                内毒素Ӱ?/td>Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.
                Accession #P31041
                背景T-cell-specific surface glycoprotein CD28, contains an Ig-like V-type domain. CD28 is one of the proteins expressed on T cells that provide co-stimulatory signals, which are required for their activation. It is the receptor for CD80 and CD86. When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen presenting cells (APCs). The CD86 expression on antigen presenting cells is constitutive. CD28 is the only B7 receptor constitutively expressed on naive T cells. It involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival.
                溶解方法Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
                保存方法Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
                纯度Greater than 95% as determined by reducing SDS-PAGE.
