About this compound
Oxytocin 5 mg - Peptide Hormone for Neuroendocrine & Behavioral Research
- Composition: 5 mg Oxytocin (lyophilized peptide powder)
- Category: Peptide Hormone
- Form: Multi-dose vial with freeze-dried powder
What is Oxytocin?
Oxytocin is a naturally occurring peptide hormone produced in the hypothalamus and released by the posterior pituitary gland. It is widely studied for its role in neuroendocrine signaling, social behavior, stress response, and reproductive biology.
In research settings, Oxytocin is associated with the modulation of central nervous system pathways, hormonal regulation, and receptor-mediated cellular signaling.
Unlike peptides primarily focused on growth hormone, metabolic, or tissue repair pathways, Oxytocin is mainly investigated for its effects on oxytocin receptor activation, neuroendocrine communication, and behavioral signaling. In research settings, Oxytocin has shown relevance in social bonding research, stress and anxiety models, and reproductive physiology studies.
Relevant for neuroendocrine signaling, behavioral research, oxytocin receptor studies, and hormonal regulation.
Key Research Insights
Neuroendocrine Signaling: Studied for its role in communication between the nervous system and endocrine pathways.
Behavioral Research: Investigated in research models related to social interaction, bonding behavior, and emotional regulation.
Stress Response Research: Explored for its involvement in stress adaptation, anxiety-related pathways, and hypothalamic signaling.
Reproductive Biology: Relevant in studies focused on reproductive physiology, uterine signaling, and lactation-related mechanisms.
Storage Guidelines
- Store at 2-8 °C (36-46 °F).
- Protect from light and moisture.
- Do not freeze.
- Avoid temperature fluctuations.
Why Choose Oxytocin?
Oxytocin is regarded as a highly relevant peptide hormone for neuroendocrine and behavioral research.
Its well-documented receptor activity, central role in hormonal signaling, and broad relevance in nervous system research make it a valuable research tool for studies focusing on behavior, stress response, reproductive biology, and endocrine regulation.
Order Oxytocin 5 mg - and advance your research in neuroendocrine signaling, behavioral pathways, and hormonal science.
