CXCL15 蛋白, Mouse (HEK293, His)

CXCL15, also known as Lungkine or WECHE, is a member of the ELR motif-containing CXC chemokines. CXCL15 has neutrophil chemotactic activity. CXCL15 is high expression in the lungs of mice^[1][2]. CXCL15 Protein, Mouse (HEK293, His) is produced in HEK293 cells with six C-Terminal His-tags. It consists of 142 amino acids (Q26-A167).

CXCL15 (Lungkine) 是一种 ELR+ CXC 趋化因子，在发育中的肺中具有中性粒细胞趋化特性。CXCL15 具有与免疫学和宿主防御系统相关的活性^[1][2]。

Recombinant mouse CXCL15 (5-20 ng/mL; for 4 days) decreases numbers of functional hematopoietic progenitor cells during cytokine-enhanced ex-vivo culture of lineage negative mouse bone marrow cells. Moreover, CXCL15, through S-Phase specific actions, is able to suppress in vitro colony formation of normal wildtype mouse bone marrow granulocyte macrophage (CFU-GM), granulocyte (CFU-G), macrophage (CFU-M), BFU-E, and multipotential (CFU-GEM)^[1].

Recombinant mouse CXCL15 (200 ng/mouse; i.p.; once) increases migration of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) only in the isotype control group, but not in mice that received CXCR2 blockade^[4].

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
