- During ultrafiltration in a hollow fiber device 105 liters of lipase frort Pseudomonas fluorescens was concentrated to 4 liters with a yield of 56% of total initial activity. The concentrated lipase solution was lyophilized and purified on a DEAE-cellulose anion exchanger column. The partly purified lipase was found to probably contain carbohydrates. © 1980 Kluwer Academic Publishers.

Tidskriftsartikel (refereegranskat)abstract
- An HPLC technique is described for the analysis of organic acids in lactic acid fermented vegetables. An Aminex HPX-87 column with 0.013 M-H 2SO 4 as mobile phase was used. Separation data are presented for oxalic, citric, tartaric, malic, succinic, lactic, formic, acetic, propionic, and butyric acids. Interference problems from sugars are also reported. © 1983 J. F. Bergmann Verlag.

Purification of human basophils by affinity chromatography on anti-IgE-sepharose 6MB
- 1981
-

Tidskriftsartikel (refereegranskat)abstract
- This work describes a method for the purification of basophil leukocytes from human peripheral blood by the use of a three-step separation technique including affinity chromatography on anti-IgE-sepharose 6MB. The purity of the obtained basophils was 50--95% and the recovery was 30--40%. The basophils separated by this method appeared normal and were found to be reactive with anti-IgE in subsequent tests.
