1. An anti-N lectin was extracted from Vicia unijuga leaves with phosphate-buffered saline (PBS). Purification of the lectin was achieved, after pretreatment of the PBS extract by ammonium sulfate fractionation and absorption with human M erythrocytes, by using a combination of conventional
The purification and serological and chemical properties of Vicia graminea lectin (VGA) and Vicia unijuga lectin (VUA) were described, and then the binding-specificity of anti-M and -N antibodies and both the lectins was discussed in this review. On the basis of the facts that Vgu glycoproteins
We have previously reported that Vicia graminea lectin (VGA)- and Vicia unijuga lectin (VUA)-binding glycoproteins (Vgu glycoproteins), malignant tumor-associated antigens, exist in human meconium and amniotic fluid. To examine the origin of Vgu glycoprotein, their presence, some of their chemical
We investigated biosynthesis of Vicia graminea lectin (VGA)- and Vicia unijuga lectin (VUA)-binding (Vgu) glycoproteins, which are human malignant tumor-associated antigens, in cultured human tumor and non-tumor cells by pulse-labeling experiments with [35S]-methionine, followed by
Perchloric acid-soluble fraction prepared from a mixture of meconiums of 22 newborn babies was subjected to a systematic affinity chromatography using Vicia unijuga lectin-Cellulofine column and Arachis hypogaea lectin-Agarose column and separated into four fractions, Vgu glycoprotein, Vgu
1. Perchloric acid-soluble fraction from liver metastases of pancreas carcinoma of a patient with blood group B, was subjected to a systematic affinity chromatography using Vicia unijuga lectin (VUA) and Arachis hypogaea anti-T lectin (PNA) as immobilized ligands and separated into three fractions,
Vgu glycoprotein (Vicia graminea lectin- or Vicia unijuga lectin-binding glycoprotein) has been reported as oncofetal antigen, which is found in many kind of tumor tissues, amniotic fluid and fetal membranes. In autoradiography with an 125I-labeled Vicia unijuga lectin (VUA) probe and an
Perchloric acid-soluble fractions (PASFs) were obtained from cyst fluids of human benign ovarian mucinous cystadenoma, benign dermoid cyst, "borderline" mucinous cystadenoma, and malignant ovarian clear cell carcinoma, and from fluids of malignant embryonal carcinoma and malignant serous
Vicia graminea- and Vicia unijuga-binding glycoprotein (Vgu glycoprotein) has been reported as a malignant tumor-associated antigen, which is found in various kinds of malignant tumor-tissues and ascitic and cyst fluids of malignant tumor patients, but not found in 20 kinds of normal human tissues.
1. Twenty perchloric acid-soluble glycoprotein fractions (PASFs) were separated from carcinomatous and non-carcinomatous regions of the livers of 5 patients with primary hepatocellular carcinoma (HCC) and 5 patients with a complication of HCC and hepatocirrhosis (HC). 2. In autoradiography using
1. Perchloric acid-soluble glycoprotein fractions (PASFs) were separated, in yields of 180-610 mg per 100 ml of cyst fluid, from the cyst fluids of human ovarian cystadenomas (OCAs) in benign and borderline and ovarian clear cell carcinoma (OCC) in malignant, and then identified as glycoproteins
Perchloric acid-soluble fractions (PASFs) were separated, in yields of 87.0-151.9 mg per 1.0 g of wet meconium sample, from six samples of human meconium, and identified as glycoproteins having 41.2-74.1% carbohydrate by chemical composition analysis. Six PASFs reacted with anti-A, -B, -Lea and -Leb
