일반 설명

PHAs are carbohydrate-binding proteins. There are several types of PHAs identified, predominantly in leguminous plants.
Phytohaemagglutinin (PHA, or phytohemagglutinin) is a lectin found in plants (esp. in legumes). It is obtained from Phaseolus vulgaris (red kidney beans) and acts as a mitogen in human leucocyte culture.

애플리케이션

It has also been used as an antigen to measure in vivo T-cell-mediated immune responsiveness.
Lectin from Phaseolus vulgaris (red kidney bean) has been used in phytohemagglutinin (PHA) assay and during assessment of cellular and humoral immunity.

생화학적/생리학적 작용

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.

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 in HeLa cell cultures.

Biomarker-based tests for diagnosing TB currently rely on detecting Mycobacterium tuberculosis (Mtb) antigen-specific cellular responses. While this approach can detect Mtb infection, it is not efficient in diagnosing TB, especially for patients who lack aetiological evidence of the disease. We
