Analysis of surface carbohydrates of Trichobilharzia ocellata miracidia and sporocysts using lectin binding techniques.

Parasitology

Gerhardus MJ, Baggen JM, Van Der Knaap WP, Sminia T.
PMID: 23589931
Parasitology. 1991 Aug;103:51-9. doi: 10.1017/s003118200005928x.

Miracidia and in vitro-derived primary sporocysts of the avian schistosome Trichobilharzia ocellata were studied for the expression and the characteristics of glycoconjugate moieties comprising the surface coat. Using a panel of 9 peroxidase labelled lectins, several different lectin binding...

Cross NL, Watson SK.
PMID: 16727515
Theriogenology. 1994;42(1):89-98. doi: 10.1016/0093-691x(94)90665-6.

Binding of 12 lectins to bull sperm was analyzed to select a lectin that bound preferentially to the acrosomal region. Peanut agglutinin (PNA) and Pisum sativum agglutinin (PSA) were suitably specific for intracellular, acrosome-associated glycoconjugates. Peanut agglutinin exhibited almost...

PMID: 16661796
Plant Physiol. 1981 May;67(5):936-9. doi: 10.1104/pp.67.5.936.

Protein from the jack bean, peanut, soybean and kidney bean seeds were extracted with a solution containing 9.3 molar urea, 5 millimolar K(2)CO(3), 0.5% dithiothreitol and 2% Nonidet P-40 and then subjected to two-dimensional gel electrophoresis. After electrophoresis, the...

Fluorescent and Ferritin Labelling of Cuticle Surface Carbohydrates of Caenorhabditis elegans and Panagrellus redivivus.

Journal of nematology

Jansson HB, Jeyaprakash A, Coles GC, Marban-Mendoza N, Zuckerman BM.
PMID: 19294228
J Nematol. 1986 Oct;18(4):570-4.

Caenorhabditis elegans and Panagrellus redivivus were investigated for surface carbohydrates using fluorescent-labelled and ferritin-labelled lectins. Rhodamine-labelled Concanavalin A was specifically located in the cephalic region of both species. Rhodamine-labelled wheat germ agglutinin was located over the entire cuticle of...

Lectin histochemistry to detect altered glycosylation in cells and tissues.

Methods in molecular medicine

Brooks SA, Hall DM.
PMID: 21340890
Methods Mol Med. 2001;57:49-65. doi: 10.1385/1-59259-136-1:49.

A lectin is "a protein or glycoprotein of non-immune origin, not an enzyme, that binds to carbohydrates and agglutinates cells" (1). Lectins are naturally occurring substances, most commonly derived from plant or sometimes invertebrate sources, that can be exploited...

Effects of L-carnitine and pentoxifylline on carbohydrate distribution of mouse testicular sperm membrane.

Iranian journal of medical sciences

Aliabadi E, Karimi F, Talaei-Khozani T.
PMID: 23825890
Iran J Med Sci. 2013 Jun;38(2):107-15.

BACKGROUND: The glycoconjugate content of sperms indicates their physiological and fertility properties. Lectin reactivity is indicative of intact, capacitated, and acrosome-reacted sperms. In the epididymis, sperms experience maturation, glycoconjugate modification, and simultaneously, higher L-carnitine (LC) concentrations. The aim of...

Successful delivery following intracytoplasmic sperm injection with calcium ionophore A23187 oocyte activation in a partially globozoospermic patient.

Reproductive medicine and biology

Kamiyama H, Shimizu T, Oki T, Asada T, Araki Y, Araki Y.
PMID: 29699121
Reprod Med Biol. 2012 Mar 16;11(3):159-164. doi: 10.1007/s12522-012-0123-z. eCollection 2012 Jul.

PURPOSE: To describe a successful pregnancy outcome following intracytoplasmic sperm injection (ICSI) with assisted oocyte activation (AOA) in a case of partial globozoospermia.METHODS: AOA was accomplished with calcium ionophore A23187. Sperm morphology was observed via light, fluorescent and electron...

96-well plate format in conjunction with ultra-high-performance liquid chromatography coupled to orbitrap mass spectrometry for high-throughput screening protein binders from ginseng.

Journal of pharmaceutical and biomedical analysis
