Literature

Research context

Thymosin beta-4 is the principal G-actin sequestering protein in mammalian cells and one of the most abundant peptides in many tissue types. The literature covers actin monomer binding stoichiometry, corneal and dermal repair models in animals, cardiac progenitor signalling, and comparisons against its LKKTETQ fragment. Supplied for laboratories that require the intact sequence rather than the fragment.

Documented research areas

  • G-actin sequestration stoichiometry
  • Corneal and dermal repair models in animals
  • Cardiac progenitor cell signalling
  • Fragment versus full-length comparative work
