产品说明

包装

1, 2 mg in glass bottle
Package size based on protein content. Vial content based on protein by biuret.

生化/生理作用

PA-I has a major affinity for D-galactose and its derivatives. PA-I agglutinates all types of human and animal erythrocytes and interacts also with unicellular protozoa, algae and bacteria. PA-I induces mitogenic stimulation in cultured human lymphocytes pretreated with neuraminidase.

质量

Highly purified.

外形

Lyophilized powder containing approx. 80% protein (biuret), balance primarily sodium citrate, plus traces of calcium chloride, magnesium chloride and manganese chloride

制备说明

Purified by affinity chromatography using a modification of Gilboa-Garber.¹

分析说明

Agglutination activity is expressed in μg/ml and is determined from serial dilutions of a 1 mg/ml solution using phosphate buffered saline, pH 7.0. This activity is the lowest concentration to agglutinate a 2% suspension of neuraminidase treated human blood group A erythrocytes after one hr incubation at 25 ℃.
