A novel agglutinin gene was cloned from Arisaema lobatum using SMART RACE-PCR technology. The full-length cDNA of Arisaema lobatum agglutinin (ala) was 1078 bp and contained a 774 bp open reading frame encoding a lectin precursor (proproprotein) of 258 amino acid residues with a 23 aa signal peptide. ALA contained three mannose-binding sites (QXDXNXVXY) with two-conserved domains of 45% identit...

Myoblast cells, C2C12, which is an established cell line from satellite cells of skeletal muscle of C3H mouse, start to fuse and form multinucleated cells (myotubes) and begin to express creatine phosphokinase and myosin, when culture medium is changed from the growth medium to the differentiation medium. Among the 12 lectins that we tested, wheat germ agglutinin apparently suppressed the myotu...

Salivary agglutinin is a 300-400 kDa salivary glycoprotein that binds to antigen B polypeptides of oral streptococci, thereby playing a role in their colonization and the development of caries. A mass spectrum was recorded of a trypsin digest of agglutinin. A dominant peak of 1460 Da was sequenced by quadrupole time-of-flight (Q-TOF) tandem MS. The sequence showed 100% identity with part of the...

1. A preparation of the specific polysaccharide of Type VIII pneumococcus is described in which the use of heat, strong acid, and alkali were avoided. 2. Quantitative estimations are given of the homologous and cross reacting precipitin and agglutinin in Types III and VIII antisera produced in the rabbit and in the horse. Quantitative data are also given on the mechanism of the Type VIII precip...

Since 1933 a number of serologic tests have been made in the study of patients with rheumatic fever, arthritis, and several other diseases, who have come under the authors' care. These tests include gonococcus complement fixation, hemolytic streptococcus agglutinin and precipitin tests, and antifibrinolysin and antistreptolysin titrations. A preliminary report of the results of these was made i...

A rare case of multiple myeloma associated with severe Coombs-positive hemolytic anemia is described. A 60-year-old woman was hospitalized for acute hemolysis due to an IgG warm autoantibody with pan-agglutinin specificity. Serum and urine electrophoresis revealed the presence of a monoclonal IgGk protein and a BJk protein, respectively. Bone marrow aspirates showed diffuse infiltration with pl...
