Available Options

Select the variant that best fits your experiment. Availability and lead time may vary by option.

  • Options: Size (3) — 2 ug, 10 ug, 0.1 mg
  • Lead time: options listed as “in stock at manufacturer” typically ship in 5–7 business days; other statuses may take longer.
  • Storage: Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.

Target INTERLEUKIN-5

Recombinant Human Interleukin-5, Sf9 is supplied as a recombinant protein for in vitro research use.

Background

The protein encoded by this gene is a cytokine that acts as a growth and differentiation factor for both B cells and eosinophils. This cytokine is a main regulator of eosinopoiesis, eosinophil maturation and activation. The elevated production of this cytokine is reported to be related to asthma or hypereosinophilic syndromes. The receptor of this cytokine is a heterodimer, whose beta subunit is shared with the receptors for interleukine 3 (IL3) and colony stimulating factor 2 (CSF2/GM-CSF). This gene, together with those for interleukin 4 (IL4), interleukin 13 (IL13), and CSF2, form a cytokine gene cluster on chromosome
5. This cytokine, IL4, and IL13 are found to be regulated coordinately by long-range regulatory elements spread over 120 kilobases on chromosome 5q31.

Product format

Provided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development. Refer to the specifications table for expression format and molecular properties.

What is the purity of Recombinant Human Interleukin-5, Sf9 (Human)?
Greater than 90.0% as determined by SDS-PAGE. BioHippo includes a Certificate of Analysis (CoA) confirming purity per lot with every order.
What buffer / formulation is this protein supplied in?
Supplied as: IL5 protein solution (0.5mg/ml) contains Phosphate Buffered Saline (pH 7.4) and 10% glycerol. Reconstitute lyophilized material in sterile ultrapure water or the recommended buffer per the datasheet prior to use.
How should Recombinant Human Interleukin-5, Sf9 (Human) be stored?
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles. Prepare single-use aliquots after reconstitution to avoid repeated freeze–thaw cycles.
What expression system was used to produce this protein?
This recombinant protein was expressed in Insect (Sf9/Baculovirus). The system was selected to achieve high yield, correct folding, and appropriate post-translational modifications.
Is this protein biologically active?
Measured in a cell proliferation assay using TF-1 human erythroleukemic cell. The ED 50 for this effect is less or equal to 1.5 ng/ml. Refer to the product datasheet for recommended assay conditions and controls.
Is this protein approved for clinical or in vitro diagnostic use?
No. Supplied for Research Use Only (RUO) — not intended for therapeutic applications or in vitro diagnostic procedures.
Can I request a custom size, tag variant, or formulation?
Yes. BioHippo can accommodate custom requests including alternative sizes, His/GST/Fc tag variants, bulk quantities, and custom formulations. See the Customization & Add-ons tab or email support@biohippo.com.
