Abstract: This research aims to develop and characterize a protein drug delivery system in agarose-glucan complex. The complex was produced by sonicating the mixture of agarose-glucan components and a protein in liquid paraffin with Sonics Vibracell Processor adapted from the method of Nuo Wang et all 1997. Etanercept, an anti-tumor necrosis factor-alpha (anti-TNF-α), was used as a model protein drug which was successfully encapsulated into agarose-glucan complex system. This protein can neutralize the TNF-α, a pro-inflammatory cytokine that plays a pivotal role in regulating the inflammatory response in rheumatoid arthritis (RA) and is well-known as mediator worsening RA pathogenesis. The prepared agarose-glucan complex possesses a range of sizes, from 30 to 150 nm, dissolves well within the range of pH buffer from 5.2 to 6.2 with an average protein encapsulating efficiency up to 74.4%, and can release up to 50% of protein after 40.3 hours. This research is the basis for developing nanogel-sized targeted drug delivery in RA treatment.
