生物活性

CTOP TFA is a potent and highly selective μ-opioid receptor antagonist. CTOP TFA antagonizes the acute analgesic effect and hypermotility. CTOP TFA enhances extracellular dopamine levels in the nucleus accumbens. CTOP TFA dose-dependently enhances locomotor activity[1][2].

体内研究
(In Vivo)

CTOP TFA (0-0.5 nmol, ICV, once) antagonizes the analgesic effect in a dose-dependent manner[1].
CTOP TFA (0-2 nmol, ICV, once) causes withdrawal hypothermia and a loss of body weight in animals[1].
CTOP TFA (0-1.5 nmol per side, Intra-VTA injection) enhances extracellular dopamine levels in the nucleus accumbens and dose-dependently enhances locomotor activity[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male CFLP mice (25-30 g)[1]
Dosage: 0, 0.001, 0.05, 0.075, 0.1, and 0.5 nmol (made up in artificial cerebrospinal fluid (CSF) and kept in plastic tubes at -25℃ until use)
Administration: Intracerebroventricular (i.c.v.) administration, once
Result: Antagonized the analgesic effect in a dose-dependent manner, antagonized the induced hypermotility in a dose-dependent manner.
Animal Model: Male CFLP mice (25-30 g, Acute dependence to morphine was induced by a single dependence-inducing (100 mg/kg) dose of morphine-HC1)[1]
Dosage: 0, 0.001, 0.05, 0.2, and 2 nmol
Administration: Intracerebroventricular (i.c.v.) administration, once
Result: Decreased the body temperature in a dose-dependent manner, and caused withdrawal hypothermia and a loss of body weight in animals.
Animal Model: Long-Evans hooded rats (12, male, 350-450 g)[2]
Dosage: 0, 0.015, 0.15, and 1.5 nmol per side
Administration: Intra-VTA (ventral tegmental area) injection
Result: Enhanced extracellular dopamine levels in the nucleus accumbens, dose-dependently increased activity, whereas had no effect on feeding and drinking behavior.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
