Popis: In the downstream process of recombinant hepatitis B surface antigen (rHBsAg), nano-colloidal silica adsorbent (Aerosil-380) is one of the possible methods to separate the antigen from other main impurities partially. The current study aimed to maximize the adsorptive capacity of Aerosil-380 as well as rHBsAg recovery for large-scale production of recombinant hepatitis B vaccine. The experimental design methodology was used to optimize the eight critical parameters influencing the efficiency, rHBsAg recovery, of the adsorption-desorption process in the lab-scale. These examined parameters were the adsorption-desorption temperature, pH, contact time, agitation speed, antigen concentration, and desorption buffer. Under optimal condition, the maximum adsorption capacity of Aerosil-380 was equal to 3333 μg.g
