Merck, L8262-2MG, Lectin from Ulex europaeus (gorse, furze)

Application
Lectin from Ulex europaeus (gorse, furze) has been used:
as a Paneth cells marker in immunohistochemistry at 1:1,000 dilution
in double staining for endothelial cells for quantitation of blood vessels
in histochemical staining of bronchial epithelial cells

Biochem/physiol Actions
Ulex europaeus agglutinin has anti-H blood group specificity. There are two types of lectin: UEA I has an affinity for L-fucose and UEA II has an affinity for N,N′-diacetylchitobiose. The mol. wt. of UEA I was initially found to be 170,000 daltons. Later reports indicate that UEA I may form aggregates at neutral and basic pH and that the correct mol. wt. is 68,000 daltons.
Packaging
Package size based on protein content.
Physical form
Contains sodium citrate
Analysis Note
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 O erythrocytes after 1 hour incubation at 25 °C.
Other Notes
Conjugates are prepared from affinity purified lectin.
