PKAR-I alpha Human

Data sheet

Formulation

PKA regulatory subunit-I alpha is supplied at a concentration of 1.3 mg/ml in 20mM MOPS (pH 7.0), 150mM NaCl, 1mM 2-mercaptoethanol and 50% glycerol.

Purity

Greater than 95% as determined by SDS-PAGE.

Description

PKA regulatory subunit I a Human Recombinant is a dimeric 86kDa protein (the monomer is 381 aa 43kDa). PKAR-I alpha is purified by proprietary chromatographic techniques.

Protein Background

The Regulatory (R) subunit of Protein Kinase A (PKA) inhibits its kinase activity by shielding the Catalytic (C) subunit from physiological substrates. This inhibition is reversed in response to extra-cellular signals that increase cAMP levels in the cyto

Expression host

Escherichia Coli.

Synonyms

cAMP-dependent protein kinase type I-alpha regulatory subunit, Tissue-specific extinguisher 1, TSE1, PRKAR1A PKR1, PRKAR1, CAR, CNC, CNC1, PKR1, ADOHR, PPNAD1, ACRDYS1.

Reagent Appearance

Sterile Filtered clear solution.

Storage Conditions

PKAR-Ia should be stored at 4°C if entire vial will be used within 2-4 weeks. For long term storage it is recommended to store at -20°C. Avoid multiple freeze-thaw cycles.
