Allgemeine Beschreibung

Lectin is a carbohydrate-binding protein found in plant roots, rhizomes, leaves, seeds, and stems. Lectin is located in the cytoplasm as well as in the nucleus.

Anwendung

Lectin from Wisteria floribunda has been used:
  • to study the perineuronal nets and parvalbumin nets in mouse brain by immunofluorescence
  • to evaluate the amount of N-acetylgalactosamine (GalNAc) transferred to Gaussia luciferase (GLuc) substrates by microplate assay
  • to study its binding effects on perineuronal nets

Biochem./physiol. Wirkung

Lectin binds with high affinity to the glycans of polysaccharides, glycolipids, and glycoproteins. It is involved in plant defense.
WFA is not blood group specific, but has an affinity for N-acetyl-D-galactosamine.

Hinweis zur Analyse

Agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, of a 1 mg/ml solution. This activity is the lowest concentration to agglutinate a 2% suspension of human blood group A erythrocytes after 1 hr incubation at 25 °C.

Plants are under constant attack from pathogens and herbivorous insects. To protect and defend themselves, plants evolved a multi-layered surveillance system, known as the innate immune system. Plants sense their encounters upon perception of conserved microbial structures and damage-associated patterns

Two closely related β1,4-N-acetylgalactosaminyltransferases, β4GalNAc-T3 and β4GalNAc-T4, are thought to account for the protein-specific addition of β1,4-linked GalNAc to Asn-linked oligosaccharides on a number of glycoproteins including the glycoprotein hormone luteinizing hormone and carbonic anhydrase-6 (CA6). We have utilized soluble

Perineuronal nets (PNs) in the brains of tenascin-R-deficient (tn-r(-/-)) mice develop in temporal concordance with those of wild-type (tn-r(+/+)) mice. However, the histological appearance of PNs is abnormal in adult tn-r(-/-) mice. Here, we investigated whether similar defects are also

One major pathological process in Alzheimer's disease is mediated by hyperphosphorylated tau, which includes altered microtubules (MTs) and functions associated with tau. A potential way to compensate for altered MT function is to use an MT stabilizer, such as epothilone
