IL-2R beta/CD122 Protein, Human (Biotinylated, HEK293, His-Avi)

Cat. No.: HY-P72386
Handling Instructions

IL-2R beta (CD122), a type Ⅰ cytokine receptor expressed on T lymphocytes, is a receptor for IL-2 (Kd: 1 nM approximately). IL-2R beta mediates T cell immune responses, such as stimulating T cell proliferation and activating lymphokine-activated killer cells. IL-2R beta/CD122 Protein, Human (Biotinylated, HEK293, His-Avi) is a recombinant human extracellular region of biotinylated IL-2R beta (A27-D239) with C-Terminal 6*His tags and an Avi tag, which is produced in HEK293 cells.

Description

IL-2R beta (CD122), a type Ⅰ cytokine receptor expressed on T lymphocytes, is a receptor for IL-2 (Kd: 1 nM approximately)[1]. IL-2R beta mediates T cell immune responses, such as stimulating T cell proliferation and activating lymphokine-activated killer cells[2]. IL-2R beta/CD122 Protein, Human (Biotinylated, HEK293, His-Avi) is a recombinant human extracellular region of biotinylated IL-2R beta (A27-D239) with C-Terminal 6*His tags and an Avi tag, which is produced in HEK293 cells.

Background

IL-2R beta (CD122) is a type I cytokine receptor, and belongs to Type 4 subfamily. IL-2R beta is also a key component of the IL-15 receptor. IL-2R beta is broadly expressed in spleen, blood, and lymph node, such as B and T lymphocytes[1][3].
The sequence of amino acids in IL-2R beta differs in different species. Human IL-2R beta shares <60% aa sequence identity with mouse and rats.
IL-2R beta cytoplasmic domain heterodimerizes with IL-2 and leads to the activation of signaling pathways: phosphoinositol 3-kinase (PI3-K)/AKT, Ras-MAP kinase, and the JAK-STAT pathways[4]. IL-2R beta binds IL-2 with intermediate affinity. IL-2R beta mediates IL-2 internalization and signal transduction, such as cell proliferation or differentiation[5]. IL-2R beta interacts with IL-2 and increases the proportion of CD4+ T lymphocytes[1]. IL-2R stimulates T cell proliferation and activating lymphokine-activated killer cells[2].
IL-2R beta mediates T cell immune responses, and also mediates endocytosis, as well as transducing the mitogenic signals of IL-2.

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.

  • 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)
× = ×

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
