IL-21R Protein, Human (217a.a, HEK293, His)

Cat. No.: HY-P72559
COA Handling Instructions

IL-21R protein, a receptor for interleukin-21, forms a heterodimer with the common gamma subunit and associates with Janus kinase 1 (JAK1). These interactions are pivotal for transducing the cellular responses initiated by interleukin-21, regulating immune processes and inflammatory pathways. IL-21R Protein, Human (217a.a, HEK293, His) is the recombinant human-derived IL-21R protein, expressed by HEK293 , with C-6*His labeled tag. The total length of IL-21R Protein, Human (217a.a, HEK293, His) is 217 a.a., with molecular weight of 40-55 kDa.

Description

IL-21R protein, a receptor for interleukin-21, forms a heterodimer with the common gamma subunit and associates with Janus kinase 1 (JAK1). These interactions are pivotal for transducing the cellular responses initiated by interleukin-21, regulating immune processes and inflammatory pathways. IL-21R Protein, Human (217a.a, HEK293, His) is the recombinant human-derived IL-21R protein, expressed by HEK293 , with C-6*His labeled tag. The total length of IL-21R Protein, Human (217a.a, HEK293, His) is 217 a.a., with molecular weight of 40-55 kDa.

Background

The IL-21R protein serves as a receptor for interleukin-21. It forms a heterodimer with the common gamma subunit and associates with Janus kinase 1 (JAK1). Through this interaction, the receptor facilitates the signaling cascade initiated by interleukin-21, a cytokine with diverse immunoregulatory functions. The formation of the IL-21R heterodimer and its association with JAK1 are pivotal steps in transducing the cellular responses triggered by interleukin-21, contributing to the regulation of immune processes and inflammatory pathways.

Molecular Weight

40-55 kDa

Purity

Greater than 95% as determined by reducing SDS-PAGE.

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of 20 mM PB,150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

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

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