Research Use & Lab Practice
Definitions related to research-use-only language, laboratory protocols, experimental design, handling procedures, and compliance terminology commonly referenced in peptide research.
- Research Use Only (RUO)
- Designation indicating a material is intended solely for laboratory research and not for clinical, diagnostic, or therapeutic use.
- In Vitro
- Experiments performed outside a living organism, typically in cell cultures, plates, or test tubes.
- In Vivo
- Experiments conducted within a living organism to study biological responses in a complete system.
- Ex Vivo
- Studies performed on tissues taken from an organism but maintained outside the body.
- Assay
- A laboratory test designed to measure the presence, quantity, or activity of a compound or biological process.
- Control Group
- A reference group used for comparison to evaluate the effects of an experimental variable.
- Experimental Group
- The group exposed to the variable or compound being studied.
- Dose–Response
- The relationship between the amount of a compound and the magnitude of its observed effect.
- Endpoint
- A predefined outcome or measurement used to assess experimental results.
- Replicate
- Repeated experimental runs or samples used to confirm reliability and consistency of results.
- Blinded Study
- An experimental design in which researchers or evaluators are unaware of group assignments to reduce bias.
- Placebo
- An inactive substance used as a control to assess the true effect of an experimental compound.
- Randomization
- Assignment of subjects or samples to groups using chance to minimize selection bias.
- Standard Operating Procedure (SOP)
- A documented set of instructions designed to ensure consistent and repeatable laboratory practices.
- Good Laboratory Practice (GLP)
- A quality system covering processes and conditions under which non-clinical lab studies are planned and performed.
- Aseptic Processing
- Handling methods intended to prevent microbial contamination during preparation and experimentation.
- Cross-Contamination
- Unintentional transfer of substances between samples, potentially affecting data integrity.
- Documentation
- Accurate recording of methods, conditions, observations, and results for traceability and reproducibility.
- Data Integrity
- Assurance that data is accurate, complete, consistent, and reliable throughout its lifecycle.
- Reproducibility
- The ability to achieve consistent results when experiments are repeated under similar conditions.
- Validation
- Confirmation that a method or process performs as intended and produces reliable results.
