lyophilized
불순물
≤1% holotoxin (by CHO cell assay)
solubility
aqueous buffer: soluble
sterile distilled water: soluble
일반 설명
The pentameric cell-binding component that is responsible for binding of the holotoxin to eukaryotic cell surfaces, facilitating entry of the A protomer into receptive cells. Reported to elicit direct cellular responses by binding to several cell surface receptors with oligosaccharide side chains. Also elicits a variety of physiological responses, such as mitogenesis in human T cells, enhancement of aggregation of human platelets, elevation of cytosolic Ca2+ levels, and neutralization of antibody response in mice. Reported to deactivate CCR5 and inhibit the entry of R5 HIV-1 in activated T lymphocytes. Also blocks post-entry step of HIV-1 replication.

Exposing Chinese hamster ovary cells in culture to pertussis toxin resulted in a novel clustered growth pattern. The specificity of the response for pertussis toxin was shown by neutralization of the activity with specific anti-toxin antibody, heat lability (80 degrees

The subunit structure of islet-activating protein (IAP), pertussis toxin, has been analyzed to study a possibility that this protein is one of the A-B toxins [Gill, D. M. (1978) in Bacterial Toxins and Cell Membranes (Jeljaszewicz, J., & Wadstrom, T.

We have recently demonstrated that the binding subunit (B-oligomer) of pertussis toxin (PTX-B) deactivates CCR5 and inhibits entry of R5 human immunodeficiency virus type 1 (HIV-1) strains in activated primary T lymphocytes (M. Alfano et al., J. Exp. Med. 190:597-605

The role of the filamentous hemagglutinin (FHA) and the lymphocytosis-promoting factor hemagglutinin (LPF) in pertussis pathogenesis and immunity is the subject of active investigation. To be certain of their role as protective antigens, the hemagglutinins must be pure and free

The mechanism by which pertussis toxin induces morphological changes in Chinese hamster ovary cells was studied to determine whether the resulting clustered growth pattern is due to toxin-catalyzed ADP-ribosylation of a cellular substrate. While pertussis toxin was extremely potent in
