{"product_id":"tb-500","title":"TB-500 (Full-Length Thymosin Beta-4)","description":"\u003cp\u003eThis TB-500 listing is full-length thymosin beta-4, a synthetic counterpart of the 43-amino-acid peptide originally characterized from thymic tissue. It has the molecular formula C212H350N56O78S, a reference peptide molecular weight of 4,963.4 g\/mol excluding salt counterions, and CAS number 77591-33-4 for the reference free peptide. The peptide is notable for containing a central actin-binding domain — a region structurally complementary to actin, a major structural protein found in biology. Thymosin Beta-4 is classified as a naturally occurring intracellular peptide and is one of the most abundant members of the beta-thymosin family. \u003c\/p\u003e\u003cp\u003eSupplied as one individual 10 mg vial.
