일반 설명
Lectins are carbohydrate-binding proteins, that contains four subunits with a molecular weight of 125 kDa. Leucoagglutinin PHA-L is a plant lectin, which is transported by the neurons in the central nervous system.
애플리케이션
Lectin from Phaseolus vulgaris (red kidney bean) has been used:
- for phytohemagglutinin (PHA) swelling assay
- for lymphocyte activation assay
- to evaluate cell-mediated immune response
생화학적/생리학적 작용
Lectin agglutinates cells and precipitates polysaccharides and glycoproteins. It has anti-cancer, anti-human immunodeficiency virus (anti-HIV) and anti-microbial infection properties. Lectin is associated with toxic allergens and hemagglutinins. Lectin inhibits mucosal atrophy, lowers type 2 diabetes and obesity, enhances nutrient absorption and regulates drug targeting.
PHA consists of two molecular species, an erythroagglutinin (PHA-E) which has low mitogenic activity and high erythroagglutinin activity, and leucoagglutinin (PHA-L) which has high mitogenic and leucoagglutinating activity, but very low erythroagglutinating activity.
PHA-E is not blood group specific, but agglutination can be inhibited by certain oligosaccharides. PHA-P is the protein form of PHA prior to separation and purification of erythroagglutinin and leucoagglutinin. PHA-M is the mucoprotein form. Conjugates are prepared from the corresponding purified lectins.

Mitogenic activity at ≤10 μg per mL.
분석 메모
Agglutination activity is expressed in mg/mL and is determined from serial dilutions of a 1 mg/mL solution. This activity is the lowest concentration to agglutinate a suspension of 2% human erythrocytes in phosphate buffered saline, pH 6.8 after 1 hr incubation at 25 °C. Mitogenic activity is determined by BrdU incorporation.

Dramatic declines of native Hawaiian avifauna due to the human-mediated emergence of avian malaria and pox prompted an examination of whether island taxa share a common altered immunological signature, potentially driven by reduced genetic diversity and reduced exposure to parasites.
