Lectins are moreover versatile probes for detecting glycoconjugates in microscopy and circulation cytometric functions and for gel staining of glycoproteins. In neutral and alkaline choices, Con A exists as a tetramer with a molecular weight of roughly 104 kDa. In acidic choices (pH beneath 5.0), Con A exists as a dimer. Con A might be utilized to selectively stain the cell ground of dwell cells, and stand as much as fixation and permeabilization. When cells are mounted and permeabilized sooner than staining, fluorescent lectins stain every cell ground and organelles inside the secretory pathway.
PRODUCT DESCRIPTION
Concanavalin A (Con A) is a extensively used lectin that selectively binds to the glycoproteins, a-mannopyranosyl and a-glucopyranosy. These are usually found inside the cell wall of yeast and fungi, and the cell membrane of mammalian cells and tissues.
Stain the cell wall of yeast and fungi, and the cell membrane of mammalian cells and tissues
Detect glycoconjugates in microscopy and circulation cytometry
Stain glycoproteins in gels
Withstands fixation and permeabilization
Number of 10 CF dyes from UV to near-infrared

DESCRIPTION Utility
Concanavalin A from Canavalia ensiformis (Jack bean) has been used for creating zwitterion-immobilized molecularly imprinted polymers (ziMIPs) for protein crystallization. It has been moreover used inside the preparation of protein loaded microgels to cease enzymatic degradation of microgels for monitoring by confocal laser scanning microscope (CLSM).

Biochem/physiol Actions
Con A should not be blood group specific nonetheless has an affinity for terminal α-D-mannosyl and α-D-glucosyl residues. Ca2+ and Mn2+ ions are required for train. Con A dissociates into dimers at pH 5.6 or beneath. Between pH 5.eight and pH 7.0, Con A exists as a tetramer; above pH 7.Zero bigger aggregates are customary. Con A shows mitogenic train which depends on its diploma of aggregation. Succinylation results in an brisk dimeric sort which stays a dimer above pH 5.6.

Analysis Discover
Agglutination train: Determined from serial dilutions of a 1 mg/mL reply (this train is the underside conc. to agglutinate a 2% suspension of human erythrocytes after 1 hr incubation at 25 °C). Requires Type A Human Blood.
Concanavalin A (Con A) is probably going one of the crucial usually used lectins in cell biology. Our Alexa Fluor 488 conjugate of Con A shows the extreme, inexperienced fluorescence of the Alexa Fluor® 488 dye (absorption/emission maxima ~495/519 nm). Alexa Fluor 488 Con A selectively binds to a-mannopyranosyl and a-glucopyranosyl residues.
Uncover the Correct Stain for Your Utility
Con A and completely different lectins are carbohydrate binding proteins that acknowledge specific sugar moieties on glycoproteins. The presence and distribution of these targets fluctuate between cell varieties and tissues. In consequence, completely different cell ground stains or completely different lectin conjugates, Wheat Germ Agglutinin (WGA) Conjugates and PNA Lectin Conjugates, might produce greater ground staining and is also additional acceptable in your cell kind. Lectin conjugates might be utilized to selectively stain the cell ground of dwell cells, and stand as much as fixation and permeabilization. When cells are mounted and permeabilized sooner than staining, fluorescent lectins stain every cell ground and organelles inside the secretory pathway.
Background Non-coding RNAs and significantly microRNAs have been discovered to behave as grasp regulators of most cancers initiation and improvement. The intention of our analysis was to seek out and characterize the carry out of however functionally uncharacterized microRNAs in human breast carcinogenesis. miRNA inhibitors block miRNA regulation of purpose gene expression by safe suppression […]
Preparation Discover Prepared from peroxidase (P8375) using a modification of a broadcast method, which favors low molecular weight conjugates. Repurified after conjugation by affinity chromatography. Biochem/Physiol Actions PNA would not agglutinate common human erythrocytes, nevertheless strongly agglutinates neuraminidase dealt with erythrocytes. PNA has potent anti-T train very similar to the anti-T antibody in human sera. […]
