Structural characterization and immunomodulatory activity of a high-molecular-weight glucan-rich fraction from natural rubber serum.
Industrial natural rubber serum (NRS), a major by-product of rubber processing, is an underexplored source of structurally diverse polysaccharides. In crude Hevea latex polysaccharides (HLPs) recovered from NRS, the coexistence of multiple molecular-weight populations limits fraction-specific structural interpretation...
