Storage Instructions

All products from Research Vials are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.

Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.

Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.

Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.

Serum kisspeptin levels in women with polycystic ovary syndrome: A systematic review and meta-analysis.

The Medical journal of Malaysia 2026

INTRODUCTION: Kisspeptin is a key regulator of the hypothalamic-pituitary-gonadal axis and has been implicated in the pathophysiology of polycystic ovary syndrome (PCOS). However, reported associations between kisspeptin levels and PCOS have been inconsistent. MATERIALS AND METHODS: A systematic search of PubMed, Scopus, and Web of Science was performed from inception to August 2025 for studies comparing serum kisspeptin concentrations between PCOS patients and controls. Data extraction was cond

Kisspeptin and early pregnancy: Insights from animal models into hormonal regulation and miscarriage.

Journal of neuroendocrinology 2026

Implantation failure and early placental dysfunction are major contributors, yet the precise mechanisms remain incompletely understood. Human studies indicate that reduced placental kisspeptin is associated with recurrent pregnancy loss, while circulating kisspeptin levels increase dramatically throughout gestation and may serve as a biomarker for pregnancy viability.

Kisspeptin and neurokinin B: roles in reproductive health.

Physiological reviews 2025

Over the last two decades, research findings have considerably enhanced our understanding of the physiological regulation of the hypothalamic-pituitary-gonadal (HPG) axis and identified potential therapeutic applications. Moreover, the key role of NKB in the pathophysiology of menopausal hot flashes has led to the development of pharmacological antagonism of this pathway.

Optogenetics studies of kisspeptin neurons.

Peptides 2023

Optical systems and genetic engineering technologies have made it possible to control neurons and unravel neuronal circuit behavior with high temporal and spatial resolution. The application of optogenetic strategies to understand the physiology of kisspeptin neuronal circuits has evolved in recent years among the neuroendocrine community. Kisspeptin neurons are fundamentally involved in controlling mammalian reproduction but also are implicated in numerous other physiological processes, includi

Frequently Asked Questions

Essential information about our research-grade peptides and quality standards.

Peptides are short chains of amino acids linked by peptide bonds, typically consisting of 2-50 amino acids. They serve as the building blocks of proteins and play crucial roles in biological processes.

Research peptides are synthesized versions of naturally occurring peptides, manufactured to precise specifications for use in scientific studies.

Key characteristics: High purity (≥98%), lyophilized form for stability, accompanied by Certificates of Analysis (COA), and manufactured under strict quality control protocols.

Peptide purity refers to the percentage of the target peptide present in a sample, measured via High-Performance Liquid Chromatography (HPLC).

Our Standard: All our research peptides maintain ≥98% purity, verified by third-party laboratory testing and documented in our Certificates of Analysis.

Higher purity is critical for research because impurities can interfere with experimental results and compromise the reproducibility of studies.

All products are supplied in lyophilized powder form within sterile, sealed vials. This format provides:

  • Maximum stability: Extended shelf life compared to liquid solutions
  • Precise measurement: Researchers can work with desired quantities
  • Contamination protection: Sealed vials prevent environmental exposure
  • Shipping durability: Powder form is more stable during transit

Lyophilized peptides:

  • Store at -4°F for long-term storage (up to 24 months)
  • Store at 36-46°F (refrigerated) for short-term storage (up to 3 months)
  • Keep away from light, moisture, and repeated temperature fluctuations

We supply research-grade peptides to:

  • Academic and university research laboratories
  • Pharmaceutical and biotechnology companies
  • Independent research institutions
  • Licensed professionals conducting legitimate scientific research
