Identification of rat serum alkaline phosphatase isoenzyme by means of wheat germ agglutinin.
نویسندگان
چکیده
Wheat germ agglutinin (WGA) precipitates bone type serum alkaline phosphatase (sALP) isoenzyme specifically. The precipitates are composed of the macromolecules of WGA and "bone type sALP" (WGA-ALP complex). In order to use bone type sALP as a marker in polyacrylamide gel electrophoresis (PAGE), a method to separate "bone type sALP" from the "WGA-ALP complex" was established by using N-acetyl-D-glucosamine (GlcNAc)-Sepharose 6E column chromatography. It was concluded that this method is useful for clinical examination in the rat.

Wheat-germ agglutinin method for measuring bone and liver isoenzymes of alkaline phosphatase assessed in postmenopausal osteoporosis.
In the method of Rosalki and Foo (Clin Chem 1984;30:1182-6) bone and liver isoenzymes of alkaline phosphatase (EC 3.1.3.1) are quantified by using wheat-germ agglutinin (WGA). I suggest standardizing the procedure by using a WGA concentration that precipitates half of the alkaline phosphatase activity of serum pooled from an equal number of healthy women and men. By applying knowledge of the pr...
متن کاملAn Alkaline Phosphatase Lacking Wheat Germ Agglutinin Binding Sites Useful Enzyme for Lectin Assays with Comparable Activity to the Calf Enzyme
Despite the availability of various alkaline phosphatase (ALP) isoenzymes, the calf enzyme is being used in current enzyme assays as the detector enzyme. The glycosylation pattern of this enzyme makes it a suitable ligand for binding to wheat germ agglutinin lectin (WGA). As a result of this property, the enzyme can not be used as a conjugate with this lectin, and the calf enzyme conjugates can...
متن کاملlmmunoadsorption assay for bone alkaline phosphatase compared with wheat germ agglutinin precipitation assay in serum from (pre)pubertal girls
The performance characteristics of two bone alkaline phosphatase (ALP; EC 3.1.3.1) assays, a wheat germ agglutinin (WGA) precipitation assay and a new immunoadsorption assay (IAA), were compared. The withinand between-run imprecision of the IAA (3.6-4.2% and 3.6-7.7%) was comparable with that of the WGA assay. The mean crossreactivity with liver ALP appeared to be 4% in the WGA assay and 11 % i...

متن کاملPrecipitation of serum proteins by the lectin from wheat-germ.
We investigated the composition of the precipitate that forms when wheat-germ lectin derived from Triticum vulgaris is added to serum. A number of serum proteins are precipitated, representing about 2.5% of the total serum protein. This study demonstrates that the interaction of this lectin with the bone isoenzyme of alkaline phosphatase is not specific.
