Description
cAMP-dependent Protein Kinase (PKA) is composed of two distinct subunits: catalytic (C) and regulatory (R).Four regulatory subunits have been identified: RIα, RIβ, RIIα, and RIIβ.These subunits define type I and II PKAs.Following binding of cAMP, the regulatory subunits dissociate from the catalytic subunits, rendering the enzyme active.Type I and II holoenzymes have three potential C subunits (Cα, Cβ, or Cγ).Type II PKA can be distinguished by autophosphorylation of the R subunits, while type I PKA binds Mg/ATP with high affinity.The cAMP-dependent autophosphorylation of the human RIIα subunit occurs at Serine 99 (S99) [Entrez Protein Accession #CAA33094].Most cells express both type I and type II PKAs.Although the Rα isoforms are ubiquitously expressed, the Rβ isoforms are predominantly found in nervous and adipose tissues.In addition to their enzyme regulatory activity, the RIIα and RIIβ subunits determine the subcellular location of the holoenzymes via their interactions with specific intracellular anchoring proteins.
The I65-856.286 antibody recognizes human PKA RIIα phosphorylated at S99.

R-phycoerythrin (PE) is an accessory photosynthetic pigment found in red algae. It exists in vitro as a 240-kDa protein with 23 phycoerythrobilin chromophores per molecule. This makes PE one of the brightest fluorochromes for flow cytometry applications, but its photobleaching properties make it unsuitable for fluorescence microscopy.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light.Do not freeze.The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test.We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
