Általános leírás
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.
Alkalmazás
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
Biokémiai/fiziológiai hatások
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.

Minőség
Mitogenic activity at ≤10 μg per mL.
Analízis megjegyzés
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.

CD4 T cells harboring HIV-1/SIV represent a formidable hurdle to eradicating infection, and yet their detailed phenotype remains unknown. Here we integrate two single-cell technologies, flow cytometry and highly multiplexed quantitative RT-PCR, to characterize SIV-infected CD4 T cells directly ex

Sequence homology between SARS-CoV-2 and common-cold human coronaviruses (HCoVs) raises the possibility that memory responses to prior HCoV infection can affect T cell response in COVID-19. We studied T cell responses to SARS-CoV-2 and HCoVs in convalescent COVID-19 donors and identified a
