- 状态
- Lyophilized
- 溶解方式
- Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
- 缓冲液
- Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.
- 储存条件
- 4 °C,-80 °C
- 储存方法
- Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

- 背景
- CD28 antigen (Tp44), CD28 Molecule, CD28, MGC138290,CD28 is the receptor for CD80 (B7-1) and CD86 (B7-2) proteins.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.
- 分子量
- 18.2 kDa. Due to glycosylation, the protein migrates to 38-50 kDa based on Tris-Bis PAGE result.
