Collection, processing & handling
Samples are collected and processed using standardized protocols appropriate to the sample type. Packaging and shipping are configured for temperature-controlled logistics to preserve sample integrity for your specific workflow requirements.
Quality control & documentation
QC testing options available on request, including material-appropriate analytical checks and extended documentation. Standard documentation includes collection/processing metadata, lot identifiers, and chain-of-custody records. Custom QC panels can be configured for GLP or regulatory-facing studies.
Ordering notes
For specific donor criteria, source, volumes, or custom handling requirements, request a quote and include your study specifications. We routinely support longitudinal programs, matched sample sets, and custom collection protocols.
About the Cynomolgus Monkey
Macaca fascicularis
The cynomolgus macaque is the most widely used non-human primate in biomedical research, valued for its close physiological and immunological similarity to humans.
With over 60% genetic homology for key immune receptors, cynomolgus monkeys provide highly translatable data for drug development, making them ideal for immunology, infectious disease, and toxicology studies.
Human Similarity
~93% genetic homology with extensive immune receptor cross-reactivity
Global Availability
Multiple geographic origins with established breeding colonies
Regulatory Accepted
FDA & EMA preferred species for biologics safety assessment
Origin Lineages at a Glance
Primary Research Areas
Lactation & Drug Transfer Studies
Measure drug and metabolite transfer into milk for maternal-infant safety pharmacology and risk assessment.
Nutritional & Developmental Research
Analyze milk composition (proteins, lipids, carbohydrates, oligosaccharides) across lactation stages for infant nutrition studies.
Immunology & Passive Immunity
Study immunoglobulin (IgA, IgG) content, antimicrobial factors, and immune cells transferred via milk.
Microbiome Research
Characterize the milk microbiome and its role in infant gut colonization and immune development.
Toxicology & Environmental Exposure
Assess environmental contaminant or toxin transfer through milk in preclinical safety models.

Geographic Origins Guide
Select the optimal origin for your research requirements
Chinese Origin ★ MOST COMMON
mainland
Chinese-origin cynomolgus are no longer exported by China. Cynomolgus macaques are not native to China and were historically imported from Cambodia, Vietnam, Laos, and Indonesia. Current samples are sourced from US breeding colonies established from China-line imports.
Mauritian Origin ★ DEFINED GENETICS
island
Mauritian cynomolgus have limited MHC diversity due to founder effects, making them valuable for immunology studies requiring genetic consistency.
Cambodian Origin ★ SOUTHEAST ASIAN
mainland
Cambodian-origin animals offer a Southeast Asian source with genetics that have not been mixed with other country lineages in the same way seen in some China-line populations.
Vietnamese Origin ★ SOUTHEAST ASIAN
mainland
Vietnamese cynomolgus provide another Southeast Asian option for programs that require distinct lineage sourcing or supply chain diversification.
Indonesian Origin ★ ISLAND ORIGIN
island
Indonesian-origin cynomolgus were among the earliest origins used in preclinical research and represented one of the largest research populations before China entered the market.
Philippine Origin ★ ISLAND ORIGIN
island
Philippine-origin cynomolgus were one of the first origins used broadly in research, with a long history as a trusted and widely used model.

Our scientific team can advise on the optimal origin for your study design and regulatory requirements.
Milk is collected from lactating females via manual expression or miniature breast pump under light sedation. The nipple area is cleaned with antiseptic prior to collection, and the first few drops are discarded to minimize contamination. Collection is timed relative to last nursing when possible.
Typical yield varies by species and lactation stage: cynomolgus monkeys yield 2-10 mL, rhesus monkeys 3-15 mL, and marmosets 0.5-2 mL per collection. Peak lactation yields the highest volumes. Pooled samples from multiple collections or donors are available.
Milk is evaluated for color, consistency, and absence of visible contamination (blood, debris). Samples are collected into sterile containers and aliquoted promptly. Lactation stage, time since last nursing, and parity are documented. Fat content and total protein data available on request.
