Biochem/physiol Actions

PHA由两种分子种类组成,即具有低促有丝分裂活性和高红细胞凝集素活性的红细胞凝集素(PHA-E),和具有高促有丝分裂和白细胞凝集活性但具有非常低的红细胞凝集活性的白细胞凝集素(PHA-L)。
PHA-E不具有血型特异性,但其凝集活性可被某些低聚糖抑制。 在分离和纯化红细胞凝集素和白细胞凝集素之前,PHA-P是PHA的蛋白质形式。 PHA-M是粘蛋白形式。 结合物由相应的纯化凝集素进行制备。

Analysis Note

凝集活性以 μg/mL 表示,通过 1 mg/mL 溶液的系列稀释液测定。在 25℃ 下孵育 1 h 后,该活性是凝集 pH 6.8 磷酸盐缓冲盐水中 2% 人红细胞悬液的最低浓度。

Leprosy, caused by Mycobacterium leprae, affects over 200,000 people annually worldwide and remains endemic in the ethnically diverse, mountainous and underdeveloped southwestern provinces of China. Delayed diagnosis of leprosy persists in China, thus, additional knowledge to support early diagnosis, especially

A population at low census might go extinct or instead transition into exponential growth to become firmly established. Whether this pivotal event occurs for a within-host pathogen can be the difference between health and illness. Here, we define the principles

Nanomaterials quickly evolve to produce safe and effective biomedical alternatives, mainly silver nanoparticles (AgNPs). The AgNPs' antibacterial, antiviral, and antitumor properties convert them into a recurrent scaffold to produce new treatment options. This work reported the full characterization of a
