Enzyme-linked lectin assay (ELLA). II. Detection of carbohydrate groups on the surface of unfixed cells.
An enzyme-linked lectin assay (ELLA) has been developed to detect specific carbohydrate units on the surface of unfixed cells. The assay may be read in standard ELISA plate readers, since the cell-bound enzyme-lectin conjugate is specifically eluted from the cells prior to development of the conjugate. ELLA, when read in an enzyme-linked immunosorbent assay (ELISA) plate reader, allows better d...
متن کاملProbing multivalent carbohydrate-lectin interactions by an enzyme-linked lectin assay employing covalently immobilized carbohydrates.
We report here the synthesis of a series of mono- to trivalent N-acetylglucosamine (GlcNAc) derivatives as ligands for the plant lectin wheat germ agglutinin (WGA). Their WGA binding potencies were determined by an established enzyme-linked lectin assay (ELLA) employing microtiter plates with non-covalently immobilized porcine stomach mucin (PSM) as reference ligand and an ELLA with a new GlcNA...
متن کاملENZYME-LINKED IMMUNOSORBENT ASSAY OF NEOPTERIN USING PENICILLINASE AS LABEL
An enzyme-linked immunosorbent assay for neopterin using penicillinase as marker enzyme is reported here by polyclonal antibodies against neopterin conjugated to bovine serum albumin which were raised in rabbits. Immunoglobulin fractions were purified and coated on wells of microtiter plates. A chain heterology was introduced in neopterin derivative and conjugated to penicillinase. The assa...
متن کاملEnzyme-linked lectin assay (ELLA): use of alkaline phosphatase-conjugated Griffonia simplicifolia B4 isolectin for the detection of alpha-D-galactopyranosyl end groups.
Alkaline phosphatase has been coupled to Griffonia simplicifolia I B4 isolectin using a one-step glutaraldehyde conjugation procedure. This enzyme-lectin conjugate (AP-GS I-B4) has been used to specifically detect plastic-bound natural and synthetic glycoproteins bearing alpha-D-galactopyranosyl end groups. The extent of reactivity of the AP-GS I-B4 with the glycoproteins appears to be proporti...
متن کاملenzyme-linked immunosorbent assay
An enzyme-linked immunosorbent assay was used to titrate antisera raised against live cultures of eight type species (biotypes) of Bacteroides with the EDTA-released outer-membrane complex from 29 characterized strains of Bacteroides species. With only minor exceptions, the strains investigated reacted to titre with the antisera raised against the homologous type species and not against the het...
