In this study, a non-chromatographic method was designed based on nano-oil bodies for convenient and economical purification of the recombinant uricase. For this purpose, two chimaeras were synthesized with a different arrangement of the uricase, caleosin and intein fragments. After confirming the protein expression by measuring the uricase activity at 293\u00a0nm, purification was conducted through oil-body construction. The results were resolved on the 12% SDS-PAGE gel. Finally, the stability of the oil bodies was examined against different salts, surfactants, temperatures, and pH values. According to our results, the overexpression of uricase\u2013caleosin chimaera under the T7 promoter in <jats:italic>Escherichia coli<\/jats:italic> led to the production of soluble protein, which was successfully purified by artificial oil bodies. The active uricase was subsequently released through the self-splicing of intein. Further investigations highlighted the importance of the free C-terminus of caleosin in constructing artificial oil bodies. Moreover, surfactants and low temperature, in contrast to salts, improved the stability of oil bodies. In conclusion, caleosins are an efficient purification tag reducing the cost of purification compared to conventional chromatography methods.<\/jats:p>\n                <jats:p><jats:bold>Graphical Abstract<\/jats:bold><\/jats:p>","DOI":"10.1186\/s40643-022-00501-x","type":"journal-article","created":{"date-parts":[[2022,2,6]],"date-time":"2022-02-06T03:02:16Z","timestamp":1644116536000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Economic purification of recombinant uricase by artificial oil bodies"],"prefix":"10.1186","volume":"9","author":[{"given":"Fatemeh","family":"Saadat","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Macheroux","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Houshang","family":"Alizadeh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seyed Hadi","family":"Razavi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,2,6]]},"reference":[{"key":"501_CR1","doi-asserted-by":"publisher","first-page":"2010","DOI":"10.1093\/rheumatology\/keq204","volume":"49","author":"B \u00c1lvarez-Lario","year":"2010","unstructured":"\u00c1lvarez-Lario B, Macarr\u00f3n-Vicente J (2010) Uric acid and evolution.
