產品提供形式：

Liquid or Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
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.If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
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：

The Recombinant Human C17orf99 protein is a protein encoded by recombinant DNA that was cloned in an expression vector that supported the expression of C17orf99 gene. This recombinant C17orf99 protein was expressed in the host. The expression region is 21-265aa of the Human C17orf99. In the production, the expression vector contains N-terminal 10xHis tag and C-terminal Myc tag. Every production step was performed with a strict QC system. The purity of this protein is 90%+ determined by SDS-PAGE.
Interleukin 40 (IL-40) is a newly identified B cell-associated cytokine implicated in humoral immune responses and B cell homeostasis. As B cells play a pivotal role in autoimmunity. This cytokine was originally described by Catalan-Dibene et al. in 2017 as a small (27 kDa) secreted protein encoded by the C17orf99 gene (chromosome 17 open reading frame 99). Based on its unique structural properties, IL-40 fell into the category of the few so-called “orphan” cytokines. To date, there have been only few studies regarding the C17orf99 gene or its product IL-40 protein. It is well established that C17orf99 or IL-40 are expressed only in mammals and are particularly enhanced in fetal liver, bone marrow, and activated B cells. Very recently, C17orf99 was found down-regulated in the co-culture of human respiratory epithelial cells with macrophages upon treatment with anti-inflammatory cytokine IL-38, suggesting the role of IL-40 in inflammation. The only evidence linking IL-40 to autoimmune inflammation was reported back in 2012 by Zingaretti et al., who preliminary data indicate that IL-40 is released by RA neutrophils undergoing NETosis.
