Recombinant humaan tropomyosine-2

Source : Escherichia Coli. TPM2 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 304 amino acids (1-284a.a.) and having a molecular mass of 35.1kDa (molecular weight on SDS-PAGE will appear higher) .TPM2 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Tropomyosin beta chain isoform 2 is affiliate to the actin filament binding protein family which primarily expressed in slow, type 1 muscle fibers. Mutations in TPM2 can change the expression of other sarcomeric tropomyosin proteins, and cause cap disease, nemaline myopathy and distal arthrogryposis syndromes.

Tropomyosin 2 (beta) ||DA1||TMSB||DA2B||AMCD1||NEM4||Arthrogryposis Multiplex Congenital Distal-Type 1||beta-Tropomyosin.

Greater than 90% as determined by SDS-PAGE.

The TPM2 protein solution (0.5mg/mL) is formulated in 20mM Tris-HCl buffer (pH8.0), 1mM DTT, 100mM NaCl and 30% glycerol.

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term it is recommended to add a carrier protein (0.1% HSA or BSA) . Avoid multiple freeze-thaw cycles.
