설명

일반 설명

Pertussis toxin (PT), secreted protein exotoxin and virulence factor[1] by Bordetella pertussis, is the causative agent of whooping cough.[2] It is transported across the bacterial outer membrane through a type IV secretion system encoded by the ptl genes, situated downstream from the ptx genes that encode the toxin. This complex multisubunit toxin with an AB5 configuration, serves as a crucial component of acellular pertussis vaccines. It can function protectively as a single-component toxoid vaccine. Moreover, it is widely used in mammalian cell signaling studies due to its inhibitory effect on G-protein-coupled receptor pathways. It inhibits neutrophil recruitment and airway influx, a common inflammatory response to bacterial infection.[1]

애플리케이션

Pertussis Toxin, Bordetella pertussis has been used as a Gi protein inhibitor to study its ability to reduce the depolarizing responses of hypothalamic pro-opiomelanocortin (POMC) neurons.[3] It has also been used in pertussis toxin experiments to block Gαi for an in vivo inner ear and an in vitro outer hair cell (HC) study.[4]

생화학적/생리학적 작용

Primary Target
Guanine nucleotide-binding regulatory proteins Gi, Go, and Gt

Product does not compete with ATP.

경고

Toxicity: Toxic (F)

물리적 형태

Lyophilized from 50 mM NaCl, 10 mM sodium phosphate buffer, pH 7.0.

재구성

Following reconstitution, refrigerate (4°C). For long-term storage in solution, reconstitute with a high ionic strength buffer, such as 100 mM sodium phosphate, 500 mM sodium chloride, pH 7.0. Stock solutions are stable for at least 6 months for use in CHO cell assays and for 1-2 months for use in non-cellular systems.

Reconstitute with 500 µl H₂O. Obtain a uniform suspension before each use by scraping the walls of the tube and gently pipetting the solution to mix.
