Effects of negatively charged groups (carboxymethyl) on the calcification of poly(2-hydroxyethyl methacrylate).

Biomaterials 2002 Jul;23(14):3053-9

LHEA-GEROM, Laboratoire d'Histologie-Embryologie, Faculté de Médecine & CHU d'Angers, France.

Poly(2-hydroxyethyl methacrylate) (pHEMA) has potentially wide biomedical applications: it is biocompatible, allows immobilization of cells or bioactive molecules and has a hardness comparable to bone. We previously reported that immobilization of alkaline phosphatase (AlkP) in pHEMA can initiate mineralization in a manner that mimics the calcification of cartilage and woven bone. Because numerous proteins known to initiate mineralization possess acidic species, we have modified the neutral electrical surface of pHEMA by carboxymethylation (CM). Read More

Chromatographic analysis of the hydrophobic interactions of rabbit IgG immunoglobulins and their papain-digested fragments by bis-(p-chlorophenyl)-acetic acid coupled to aminohexyl sepharose.

K Furuya S Urasawa

Mol Immunol 1982 May;19(5):705-17

The present study revealed that the IgG immunoglobulins of normal or non-immune rabbit IgG and anti-bovine serum albumin, anti-ovalbumin, anti-bovine IgG and anti-p-chlorobenzoic acid antibodies could non-specifically bind to bis-(p-chlorophenyl)-acetic acid (DDA) coupled to omega-amino-hexyl Sepharose (AHS) by the use of strengthened hydrophobic interactions dependent on the concentration of NaCl. The main binding site on the adsorbent of DDA-substituted AHS (DDA-AHS) was found to be the DDA ligand. The hydrophobic potency of the DDA ligand was thought to be more effective than that of p-chlorobenzoic acid coupled to AHS. Read More

Synthesis and secretion of colonic glycoproteins: evidence for shedding in vivo of low molecular weight membrane components.

Biochim Biophys Acta 1980 May;629(3):553-65

In vivo glycoprotein synthesis and secretion was studied in rat colonic epithelial cells using precursor labelling with radiolabelled glucosamine. Sepharose 4B gel filtration of radiolabelled glycoproteins obtained from isolated colonic epithelial cells revealed two major fractions: (1) high molecular weight mucus in the excluded fraction and (2) lower molecular weight glycoproteins in the included volume. These glycoproteins were further fractionated by affinity chromatography on concanavalin A-Sepharose. Read More

Independent effects of IgG and complement upon human polymorphonuclear leukocyte function.

J Immunol 1976 Oct;117(4):1282-7

Particle ingestion by polymorphonuclear leukocytes (PMN) is promoted by cell surface recognition and binding of fragments of the third component of complement (C3) and Fc regions of certain immunoglobulin (IgG) molecules. In order to determine the influence of these specific ligandsurface membrane interactions upon other PMN functions, we have employed nonphagocytosable particles (serum-treated Sepharose beads) coated with fragments of C3 and/or IgG, and have investigated whether these provide a sufficient stimulus for the metabolic changes and degranulation that ordinarly accompany phagocytosis by PMN. Sepharose 4B activates complement in fresh normal serum and consequently is coated with fragments of C3 (confirmed by immunoelectrophoretic evidence of factor B and C3 conversion and by immunofluorescence).
