Interferon alpha receptor 1 (IFN-alpha R1) is a class II cytokine receptor which belongs to type I human interferons (IFNs) family. IFNs plays a role in antiviral, antiproliferative, immunomodulatory, antitumor, and antiparasitic activities by inducing transcription of IFN-stimuated genes (ISGs) through activation of the Jak-STAT pathway. Specifically, IFN- R1 is a 135-kda signal transducing subunit of the IFN alpha/beta receptor complex (IFN-alpha R) (1). IFN-alpha R1 is phospholyated through PTK- and PKC-mediated phosphorylation, which initiates docking of STAT proteins to IFNs. This leads to activation of STAT proteins by PTK-mediated phosphorylation. The mechanism behind the amplification of IFN-alpha R complex mediated transmembrane signaling has been linked to tyrosine phosphorylation on IFN-alpha R1 (2).

Concentration Calculator

The concentration calculator allows you to quickly calculate the volume, mass or concentration of your vial. Simply enter your mass, volume, or concentration values for your reagent and the calculator will determine the rest.


Molarity Calculator

Calculate the mass, volume, or concentration required for a solution.

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
