描述

IL-9 Protein, with cytokine and receptor binding activities, positively regulates cell growth. Active in the extracellular space, its human orthologs are linked to asthma and respiratory syncytial virus disease. IL-9 expression is biased, notably in testes (RPKM 6.4) and thymus (RPKM 1.0), suggesting involvement in immune and respiratory processes. IL-9 Protein, Rat (sf9, His) is the recombinant rat-derived IL-9 protein, expressed by Sf9 insect cells , with C-His labeled tag. The total length of IL-9 Protein, Rat (sf9, His) is 144 a.a., with molecular weight of ~15.6 kDa.
研究背景

IL-9蛋白表现出细胞因子活性和白细胞介素9受体结合活性，在细胞生长中发挥正向调节作用。预计它在细胞外空间中活跃。该基因的人类直系同源物与哮喘和呼吸道合胞病毒感染性疾病有关。IL-9 的表达存在偏差，在睾丸 (RPKM 6.4) 和胸腺 (RPKM 1.0) 中观察到显着水平，表明其可能参与免疫和呼吸过程。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
