IFN-alpha/beta R2 Protein, Mouse (Biotinylated, HEK293, His, Avi)

Art. -Nr.: HY-P703997
Handling Instructions Technical Support

IFN-α/β R2 protein and IFNAR1 together constitute the heterodimeric receptor of type I interferon and initiate the JAK-STAT signaling cascade. Upon binding of type I interferons, IFNAR1 and IFNAR2 activate related Janus kinases (TYK2 and JAK1) in proximity, resulting in cross-phosphorylation. IFN-alpha/beta R2 Protein, Mouse (Biotinylated, HEK293, His, Avi) is the recombinant mouse-derived IFN-alpha/beta R2 protein, expressed by HEK293, with C-Avi and C-His labeled tag.

Beschreibung

IFN-α/β R2 protein and IFNAR1 together constitute the heterodimeric receptor of type I interferon and initiate the JAK-STAT signaling cascade. Upon binding of type I interferons, IFNAR1 and IFNAR2 activate related Janus kinases (TYK2 and JAK1) in proximity, resulting in cross-phosphorylation. IFN-alpha/beta R2 Protein, Mouse (Biotinylated, HEK293, His, Avi) is the recombinant mouse-derived IFN-alpha/beta R2 protein, expressed by HEK293, with C-Avi and C-His labeled tag.
Background

The IFN-alpha/beta R2 Protein, in conjunction with IFNAR1, constitutes the heterodimeric receptor for type I interferons, encompassing interferons alpha, beta, epsilon, omega, and kappa. Upon type I interferon binding, the receptor activation initiates the JAK-STAT signaling cascade, leading to the transcriptional activation or repression of interferon-regulated genes that mediate the interferon response. Mechanistically, the binding of type I interferon brings IFNAR1 and IFNAR2 into close proximity, facilitating cross-phosphorylation of their associated Janus kinases (JAKs), with TYK2 bound to IFNAR1 and JAK1 bound to IFNAR2. The activated JAKs then phosphorylate specific tyrosine residues on the intracellular domains of IFNAR1 and IFNAR2, creating docking sites for STAT transcription factors (STAT1, STAT2, and STAT). These phosphorylated STAT proteins translocate into the nucleus, regulating the expression of interferon-regulated genes. Additionally, IFN-alpha/beta R2 proteins may function as potent inhibitors of type I interferon receptor activity, showcasing their role in modulating the interferon signaling pathway.

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
