Description

LEP(116-130)(mouse) is a synthetic leptin peptide fragment.

In Vitro

LEP-(116-130) (300 µM) is unable to inhibit AP-OB binding[1].

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

In Vivo

LEP-(116-130) (1 mg, i.p.) results in a reduced rate of body weight gain in the presence of increased food intake compared with vehicle-injcted control mice. LEP-(116-130) significantly reduces blood glucose levels by appr 100 mg/dL. Administration of LEP-(116-130) to wild-type (+/+) C57BLKS/J-m mice for 4 or 7 days has no effect on their ability to thermoregulate[1].

Animal Administration
[1]

Blood is drawn from the tail vein of each mouse 2 h before the onset of the dark period at the beginning of the study (day 0) and after 2, 4, and 6 days of treatment with 1 mg/day i.p. LEP-(116-130). Blood glucose levels are determined with a Glucometer Elite blood glucose monitor. After 4 and 7 days of treatment with 1 mg/day i.p. LEP-(116-130), sensitivity to cold is examined by placing the mice without food or water in a cold room with an ambient temperature of 4°C. Body temperature is measured with a rectal probe every hour for 4 h.

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.
