  • Cat.No.
  • CSC-CTK0113
  • Description
  • Activin A is a TGF-beta family member that exhibits a wide range of biological activities including regulation of cellular proliferation and differentiation, and promotion of neuronal survival. Elevated levels of Activin A in human colorectal tumors and in post-menopausal woman have been implicated in colorectal and breast cancers, respectively. The biological activities of Activin A can be neutralized by inhibins and by the diffusible TGF-beta antagonist, Follistatin. Human Activin A is a 25 kDa disulfide-linked homodimer. It has been purified by proprietary chromatographic techniques. Please note: Recombinant human Activin A is identical to recombinant mouse and rat Activin A as numerous literary sources demonstrating the complete identity of the mature Activin A sequence among these three species.
  • Species
  • Human
  • Product Overview
  • Human SMAD2 expressed in HEK cells
  • Molecular Mass
  • 25 kDa
  • Size
  • CAT# CSC-CTK0113-5 (5 μg); CAT# CSC-CTK0113-25 (25 μg)
  • Expression System
  • HEK cells
  • Purity
  • Greater than 95% as determined by SDS-PAGE analysis.
  • Activity
  • rHu Activin A is fully biologically active when compared to a standard. The specific activity was determined by the dose-dependent inhibition of proliferation of the MPC-11 cell line (mouse plasmocytoma cell line) and is typically 0.5-5 ng/ml.
  • Endotoxin Level
  • Less than 1 EU/μg.
  • Formulation
  • Sterile-filtered, white, lyophilized (freeze-dried)powder. Lyophilized from a concentrated protein solution (1 mg/ml) in 1xPBS.
  • Reconstitution
  • Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
  • Storage & Stability
  • The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rHu Activin A should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long term storage, it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze/thaw cycles.
