Molecular Characterization

TXN2(Thr 60 - Gly 166)AAH13726

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 12.8 kDa. The protein migrates as 13 kDa under reducing (R) condition (SDS-PAGE).


Less than 1.0 EU per μg by the LAL method.


>97% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH8.0. Normally trehalose is added as protectant before lyophilization.

Thioredoxin-2 (TXN2),a member of the thioredoxin family,is also known as mitochondrial (MTRX or Mt-Trx) and TRX2.TXN2 have two important domains: Redox-active center and Transit peptide. TXN2 has an anti-apoptotic function and plays an important role in the regulation of mitochondrial membrane potential. Also, TXN2 could be involved in the resistance to anti-tumor agents. TNX2 possesses a dithiol-reducing activity as well.
