Recombinant Human PACT protein (His tag)

Product Specifications

Background

Activates EIF2AK2/PKR in the absence of double stranded RNA (dsRNA), leading to phosphorylation of EIF2S1/EFI2-alpha and inhibition of translation and induction of apoptosis. Required for siRNA production by DICER1 and for subsequent siRNA-mediated post-transcriptional gene silencing. Does not seem to be required for processing of pre-miRNA to miRNA by DICER1.

Abbreviation

PACT

Synonyms

Interferon-inducible double-stranded RNA-dependent protein kinase activator A; PKR-associated protein X; PRKRA

< 10 EU/mg of the protein as determined by the LAL method.

Purity

> 95% as determined by reducing SDS-PAGE.

Bioactivity

Not validated for activity

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.

Shipping Conditions

This product is provided as lyophilized powder which is shipped with ice packs.

Storage Conditions

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
