Glossary Terms (Simple List)
-
Transfectoma
Cells expressing exogenous proteins or reporter genes, produced by the transfection of continuously growing cells with gene expression constructs. (TR50)
-
Transfer Disinfection
A disinfection process conducted on materials and equipment that coats the surface for a validated wetted time to remove bioburden prior to introducing such items into classified areas. (TR70)
-
Transition Analysis
Mathematical evaluation of the chromatogram tracing as the mobile phase changes from one solution to another. An alternative to HETP and peak asymmetry for evaluating column packing and performance. (TR14)
-
Transmembrane Pressure (TMP)
The pressure difference equal to the average feed-stream pressure minus the average filtrate-stream pressure. TMP = (Pfeed + Pretentate)/2 - Pfiltrate (TR15)
-
Transmission Electron Microscopy (TEM)
A microscopy technique whereby a beam of electrons is transmitted through an ultra-thin specimen, interacting with the specimen as it passes through it. An image is formed from the electrons transmitted through the specimen, which are magnified and focused by an objective lens, and appear on an imaging screen. (TR41)
-
Transport Service Agreement
A contractual agreement that describes the legal, logistical, technical and quality terms or contractual arrangements between shippers and transport services providers. Different names might be used for this type of agreement in different companies. (TR39)
-
Transport Service Provider
Contracting party who mediates or executes the transportation of medicinal products on behalf of the shipper. (TR39)
-
Transportation Service Providers (TSP)
Companies that physically transport the product. (TR52)
-
Transportation Study
Study performed to generate data to evaluate the effect of temperature variation on the product during transportation on product quality. Other test, such as vibration, pressure, and drop tests, may be considered. (TR39)
-
Trend
A statistical term referring to the direction or rate of change of a variable(s) (ICH Q9). (TR54) (TR54-2)
