S Kelly et al.
Clinica chimica acta; international journal of clinical chemistry, 97(2-3), 239-242 (1979-10-01)
A fluorimetric assay for leukocyte acid lipase, the enzyme defect in Wolman disease, is described. The method requires a smaller volume of blood and can be performed more rapidly than the present colorimetric assay for the leukocyte enzyme.
M W Baillargeon et al.
Lipids, 26(10), 831-836 (1991-10-01)
Lipases from Geotrichum candidum NRRL Y-553 are of interest because of their unique specificity for cis-9-unsaturated fatty acids relative to both stearic and palmitic acids. The lipases were partially purified by chromatography on Octyl Sepharose, AG MP-1 macroporous anion exchanger
