IL-9 Protein, Rat (sf9, His)

Cat. No.: HY-P73230
Handling Instructions

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.

Background

IL-9 Protein exhibits cytokine activity and interleukin-9 receptor binding activity, playing a role in the positive regulation of cell growth. It is predicted to be active in the extracellular space. Human ortholog(s) of this gene have been implicated in asthma and respiratory syncytial virus infectious disease. The expression of IL-9 is biased, with notable levels observed in testes (RPKM 6.4) and thymus (RPKM 1.0), indicating its potential involvement in immune and respiratory processes.

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.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

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

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

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
