Abstract[English]
Disclosed herein include methods, compositions, and kits suitable for use in preservation (e.g., cryopreservation) of samples. The composition (e.g., cryopreservation reagent) can comprise: one or more cryoprotective agent(s), one or more culture media component(s), one or more carbohydrate(s), and/or one or more amino acid(s). The composition can be capable of maintaining one or more cellular properties and/or cell viability of a plurality of cells in a sample for a period of time under a storage condition. Also provided are methods of sample preservation and sample analysis. The method can comprise contacting a sample with the cryopreservation reagent, thereby generating a shielded sample. The method can comprise exposing the shielded sample to a freezing storage condition, thereby generating a cryopreserved sample.[French]
L'invention concerne des procédés, des compositions et des kits appropriés pour une utilisation dans la conservation (p. ex. la cryoconservation) d'échantillons. La composition (p. ex. un réactif de cryoconservation) peut comprendre : un ou plusieurs agents cryoprotecteurs, un ou plusieurs composants de milieux de culture, un ou plusieurs glucides et/ou un ou plusieurs acides aminés. La composition peut permettre de maintenir une ou plusieurs propriétés cellulaires et/ou une viabilité cellulaire d'une pluralité de cellules dans un échantillon pendant une certaine durée dans une condition de stockage. L'invention concerne également des procédés de conservation d'échantillons et d'analyse d'échantillons. Le procédé peut consister à mettre en contact un échantillon avec le réactif de cryoconservation, générant ainsi un échantillon protégé. Le procédé peut consister à exposer l'échantillon protégé à une condition de stockage de congélation, générant ainsi un échantillon cryoconservé.
