Usage
Aqueous two-phase separation (ATPS) is a liquid-liquid fractionation technique effectively used for protein separation and purification[1]. When a protein fuses with a hydrophobin, the hydrophobin changes the hydrophobicity of the protein, which causes the protein to aggregate into the surfactants. Our team is trying to improve traditional ATPS by incorporating a continuous-flow system and replacing fungal hydrophobins with BslA. Using EBFP[2] as target proteincan visually observe fluorescent protein (EBFP,target protein) showing blue fluorescence in the process of protein expression and two-phase extraction, so as to determine the separation and purification effect.
Biology
Blue fluorescent protein (BFP)[3] was mutant of GFP which originally identified from the jellyfish (Aequorea victoria). Design Consideration: The construct was cloned into a PET28a plasmid and transformed into EBFP-PET28a [2] The construction includes: EBFP is fused with BslA with a GS linker（GGTGGTGGCGGCAGCGGCGGAGGCGGTAGT） and TEVlinker（GAAAACCTGTACTTCCAGGGTTCTGGT）
