Abstract (en)

[origin: WO8701128A1] A yeast cell lysis buffer for enhancing the recovery of subcellular particles including an aqueous solution of a nonionic detergent at a concentration within the range of about 0.5% to about 1.0% by volume at a temperature within a range from about 3<o>C to about 8<o>C. Triton X-100 <R> is a preferred nonionic detergent for use in the lysis buffer. This lysis buffer may be employed in a method of extracting subcellular particles (e.g. HBsAg particles) from cells (e.g. genetically transformed yeast cells) which are broken open in the presence of the lysis buffer.
