生物活性
IL-23 (IL-23 alpha & IL-12 beta Heterodimer) Protein is a recombinant protein dimer complex containing rat-derived IL-23 alpha & IL-12 beta Heterodimer protein, expressed by HEK293. The IL-23 alpha protein has cytokine activity and binds to interleukin-23 receptors. It regulates cytokine production, lymphocyte activation, and peptidyl-tyrosine phosphorylation. It influences T cell proliferation and RNA polymerase II transcription. Found in the extracellular space, it is part of the interleukin-23 complex. It is mainly expressed in the thymus, spleen, and other tissues. It is orthologous to the human IL23A gene encoding interleukin 23 subunit alpha.
The recombinant rat IL23A & the rat IL12B comprises 510 (186+324) amino acids and has a calculated molecular mass of 58.2 (21+37.2) KDa. A DNA sequence encoding the rat IL23A (Met1-Ala196) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the rat IL12B (Met1-Ser335) was expressed with a polyhistidine tag at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the rat IL23A & the rat IL12B heterodimer was purified.
Measured by its ability to induce IL17 secretion by mouse splenocytes, the ED50 for this effect is 0.5-3ng/mL.
Endotoxin < 1 EU/µg
Apparent Molecular Weight: approximately 47.08, 43.29, 27.67 and 24.75 KDa respectively in SDS-PAGE
Lyophilized from sterile PBS, pH 7.4.
实验参考
建议您制定动物给药及实验方案时，尽量参考已发表的相关实验文献（溶剂种类及配比众多，简单地溶解目的化合物，并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题，未必能保证目的化合物在动物体内充分发挥生物学效用）。
体内实验的工作液，建议您现用现配，当天使用；如在配制过程中出现沉淀、析出现象，可以通过超声和（或）加热的方式助溶。
切勿一次性将产品全部溶解。
请在下面的计算器中，输入您的动物实验相关数据并点击计算，即可得到该实验的总需药量和工作液终浓度。
例如您给药剂量是10 mg/kg，平均每只动物的体重为20 g，每只动物的给药体积是100 μL，动物数量为20只，则该动物实验的总需药量为4 mg，工作液终浓度为2 mg/mL。
1：鉴于实验过程的损耗，建议您至少多配1-2只动物的量；
2：为该产品最终给药时的浓度。
