Description

IFN-alpha 6 (IFNA6), belongs to type I interferon family, is produced by macrophages with antiviral activities[1]. IFN-alpha 6/IFNA6 Protein, Human (HEK293, His) contains 169 a.a. (S21-E189), produced in HEK293 cells with a C-terminal His-tag.

Background

IFN-alpha 6 (IFNA6; IFN-α6), belongs to the alpha/beta interferon (IFN) family, is produced by the macrophages with antiviral activities[1]. Interferon (IFN) is originally identified as a substance ‘interfering’ with viral replication in vitro. IFN-α/β and related molecules are classified as type I IFNs, as for the other two types of type II IFN (IFN-γ) and type III IFNs (IFN-λ), respectively[2].
Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. Interferon alpha (IFNa) shows significant biological activity in various cancers, paticularly haematological malignancies such as hairy cell leukaemia and chronic myelogenous leukaemia[3].
Type I interferons (IFNs) are produced early in response to viral infection and modulate adaptive immunity. IFN-alpha 6 involves in acute myocarditis and chronic cardiac inflammation inhibition, promotes systemic murine cytomegalovirus (MCMV) infection by reducing MCMV replication[4].
As for a wildly use of IFN in animal model, the sequence of amino acids in IFNA6 protein of human is very different from mouse (56.61%)

In Vivo

Humanized IFN-alpha 6 (IFNA6) shows protection on systemic murine cytomegalovirus (MCMV) infection and myocarditis by DNA-inoculated manner, and reduces MCMV replication[4].

Molecular Weight

Approximately 18 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.

  • Dilution Calculator

  • 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)
× = ×
C1   V1   C2   V2

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
