Lectin from Ulex europaeus (gorse, furze) has been used:
as a Paneth cells marker in immunohistochemistry at 1:1,000 dilution [1]
in double staining for endothelial cells for quantitation of blood vessels[2]
in histochemical staining of bronchial epithelial cells[3]
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.
Linkage
Conjugates are prepared from affinity purified lectin.
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.

Here, we exploit an absolute differential between stem and progeny cells in their ability to express Cre from a somatically inducible transgene to determine the longevity of intestinal Paneth cells. In the Ahcre transgenic line induction of Cre recombinase allows

The aggregation of lymphoid cells in the bronchial mucosa has been named the bronchus-associated lymphoid tissue (BALT) and investigated in comparison with the gut-associated lymphoid tissue (GALT). To elucidate precisely the structure and function of the BALT, the present study
The purpose of this study was to assess vascular and histological alterations in two COVID-19 and three control post-mortem retinas. The macular areas of flat-mounted samples were processed for immunofluorescence. Lectin and collagen IV positive vessels were captured under confocal
Glycoconjugates in the olfactory system play critical roles in neuronal formation, and α1-2 fucose (α1-2Fuc) glycan mediates neurite outgrowth and synaptic plasticity. Histochemical findings of α1-2Fuc glycan in the mouse olfactory system detected using Ulex europaeus agglutinin-I (UEA-I) vary. This
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease involving progressive degeneration of upper and lower motor neurons. The pattern of lower motor neuron loss along the spinal cord follows the pattern of deposition of phosphorylated TDP-43 aggregates. The blood-spinal
