BoxB recapitulates the cytokine activity of full length HMGB1 and efficiently activates macrophages to release tumor necrosis factor (TNF- ) and other proinflammatory cytokines (Li et al 2004). This product contains four amino acids (MARI) that have been added at the N terminus for the purpose of expression in bacteria. It contains only trace amounts of LPS (<0.4 ng/mg protein).
