Summary

Recombinant human IFNβ is an 20.0 kDa protein containing 166 amino acid residues. Due to glycosylation, IFNβ has an approximate MW of 22.3 kDa based on SDS-PAGE gel and Mass Spectrometry.

APPLICATION

Application Note

1. Measured by its ability to induce apoptosis in HeLa cells. The expected ED₅₀ for this effect is 20-30 ng/ml.
2. Determined by its ability to stimulate the proliferation of human TF-1 cells. The expected ED₅₀ is < 0.1 ng/ml, corresponding to a specific activity of > 1 x 10⁷ units/mg.

Background

This gene encodes a cytokine that belongs to the interferon family of signaling proteins, which are released as part of the innate immune response to pathogens. The protein encoded by this gene belongs to the type I class of interferons, which are important for defense against viral infections. In addition, type I interferons are involved in cell differentiation and anti-tumor defenses. Following secretion in response to a pathogen, type I interferons bind a homologous receptor complex and induce transcription of genes such as those encoding inflammatory cytokines and chemokines. Overactivation of type I interferon secretion is linked to autoimmune diseases. Mice deficient for this gene display several phenotypes including defects in B cell maturation and increased susceptibility to viral infection. [provided by RefSeq, Sep 2015]
