An authoritative analysis of native and recombinant Thymosin Beta-4 (CAS NO: 77591-33-4 / 885340-08-9), exploring primary peptide sequences, actin-sequestering stoichiometry, and critical differences versus TB-500 synthetic fragments.
Thymosin Beta-4 (Tβ4) is a naturally occurring, water-soluble 43-amino-acid peptide with an acetylated N-terminus. Its chemical nomenclature corresponds to N-Acetyl-L-seryl-L-alpha-aspartyl-L-lysyl-L-prolyl-L-alpha-aspartyl-L-methionyl-L-alanyl-L-alpha-glutamyl-L-isoleucyl-L-alpha-glutamyl-L-lysyl-L-phenylalanyl-L-alpha-aspartyl-L-lysyl-L-seryl-L-lysyl-L-leucyl-L-lysyl-L-lysyl-L-threonyl-L-alpha-glutamyl-L-threonyl-L-glutaminyl-L-alpha-glutamyl-L-lysyl-L-asparaginyl-L-prolyl-L-leucyl-L-prolyl-L-seryl-L-lysyl-L-alpha-glutamyl-L-threonyl-L-isoleucyl-L-alpha-glutamyl-L-glutaminyl-L-alpha-glutamyl-L-lysyl-L
