Medchemexpress LLC PKI-beta Human His 50ug
PKI-beta is a recombinant human protein that functions as a potent, competitive inhibitor of cAMP-dependent protein kinase (PKA). Expressed in Escherichia coli with an N-terminal 6xHis tag, it is supplied as a filtered, glycerol-containing buffered solution and is purified for use in in vitro biochemical assays that require selective inhibition of PKA catalytic activity.
- Recombinant human isoform-1 (M1-K78) for biological relevance.
- Potent competitive inhibition of PKA catalytic subunit.
- N-terminal 6xHis tag for affinity purification or detection.
- >95% purity confirmed by reducing SDS-PAGE.
- Stabilized glycerol-containing formulation for improved shelf life.
- Available in small-scale sizes (10 μg, 50 μg, 100 μg) for assay flexibility.
