產品提供形式：

Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

3-7 business days
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
產品描述：

Human ICOS ligand (ICOSLG) amino acid Asp19-Ser258, with an N-terminal linker, and a C-terminal 6xHis-tag, was expressed in mammalian cells. The product is the recombinant human ICOSLG protein. It is an active protein whose bioactivity has been measured by its binding ability with the human ICOS receptor in a functional ELISA. The EC₅₀ of human ICOSLG protein is 29.04-43.59 ng/ml. The purity of this ICOSLG protein reaches up to 95% determined by SDS-PAGE. It has an apparent molecular mass of 40 kDa on SDS-PAGE while its predicted mass is 28.9 kDa. Glycosylation causes this result. Its endotoxin level is less than 1.0 EU/ug measured by the LAL method. And it is in stock now.

ICOSLG is the ligand for inducible costimulatory molecule (ICOS). ICOS-ICOSLG interaction delivers the co-stimulatory signals that facilitate the activation and differential of T cells. Dysregulation of the ICOS-ICOSLG pathway has been associated with autoimmune diseases and cancer and is a potential immune checkpoint blockade.

靶點詳情

功能：

Ligand for the T-cell-specific cell surface receptor ICOS. Acts as a costimulatory signal for T-cell proliferation and cytokine secretion; induces also B-cell proliferation and differentiation into plasma cells. Could play an important role in mediating local tissue responses to inflammatory conditions, as well as in modulating the secondary immune response by co-stimulating memory T-cell function.
亞細胞定位：

Cell membrane; Single-pass type I membrane protein.
蛋白家族：

Immunoglobulin superfamily, BTN/MOG family
組織特異性：

Isoform 1 is widely expressed (brain, heart, kidney, liver, lung, pancreas, placenta, skeletal muscle, bone marrow, colon, ovary, prostate, testis, lymph nodes, leukocytes, spleen, thymus and tonsil), while isoform 2 is detected only in lymph nodes, leuko
