  • 应用备注

    Optimal working dilution should be determined by the investigator.

    说明

    Biological activity: Activity was tested by induction of IL-6 in human skin fibroblasts by IL-17A/F. The ED50 is 15-25 ng/ml, corresponding to a specific activity of 6.6 - 4 x 104 units/mg.

    限制

    仅限研究用
  • 状态

    Liquid

    溶解方式

    For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored from -20 °C to -70 °C. Stock solutions can also be prepared at 50-100 μg/mL in sterile buffer (PBS, HPBS, DPBS, or EBSS) containing carrier protein such as 0.2-1 % BSA or HSA and stored in working aliquots at -20 °C to -70 °C.

    缓冲液

    0.22 μm filtered protein solution is in 10 mM NaH2PO4, 300 mM NaCl, pH 7.2.

    注意事项

    Avoid repeated freeze/thaw cycles.

    储存条件

    -20 °C

    储存方法

    Unopened vial can be stored between 2°C and 8°C for one month, at -20°C for six months, or at -70°C for one year.

    背景

    IL-17A/F is part of the IL-17 cytokine family which consists of six structurally related proteins (IL-17A, B, C, D, E, and F). IL-17A is expressed primarily by Th17 cells, a subset of CD4 T cells. IL-17F is most closely related to IL-17A. The two molecules share 50 % aminoacid sequence homology. Like IL-17A, IL-17F mRNA and protein have been detected in Th17 cells. IL-17F and IL-17A exist as a homodimers, adopting a cysteine knot motif formed through the interactions of four cysteines, one of which is responsible for the interchain bonding. IL-17F and IL-17A can form both homodimeric and heterodimeric proteins when expressed in a recombinant system and all forms of the recombinant proteins have in vitro functional activity. In addition, activated human CD4-T cells produce the homodimers of IL-17F, IL-17A, and the IL-17F/IL-17A heterodimer.
