Stabilization freezing

Stability freeze-thawing of tissue or fibroblast lysates may result in reduced PTPS activity, and it is thus recommended to assay activity always from freshly lysed material. However, lysates may be kept for 1-2 days at -80°C. [Pg.693]

Specifications and Standards. Borax stability is an important property in adhesives, paper, and textile applications. Ollier emulsion properties tabulated by manufacturers include tolerance to specific solvents, surface tension, minimum film-forming temperature, dilution stability, freeze-thaw stability, percent soluble polymer, and molecular weight.

Table 2 gives some examples of excipients used as stabilizers for proteins in freeze-dried formulations. Among others, saccharides are the most widely used excipients for stabilizing freeze-dried therapeutic proteins. There are exceptions to the need for stabilizing excipients, e.g., recombinant (ot-Antitrypsin was stable when freeze-dried alone or with lactose, sucrose, and polyvinylpyrrolidone. ... [Pg.1648]

Derivatization to stabilize, freeze-drying, and storage at 4°C, far from light or air exposition, in case it is reactive or thermally or hydrolytically unstable. [Pg.1400]

Other approaches to studying transient species involve some kind of stabilization. Freeze-quenching and chemical stabilization have been used. Freeze-quenching is quite common for macromolecular radicals and metal ions, whereas chemical stabilization (e.g., by spin trapping) is more usual for small radical species. [Pg.72]

Portions of these paints were oven aged for 10 days at 60 °C, as an indication of long-term stability. Freeze-thaw tests were also run that consisted of five cycles at -25 °C. [Pg.545]

Sample Stability. Experiments demonstrating sufficient stability of the analyte in the sample matrix must be included in prestudy validation. Such experiments should mimic as closely as possible the conditions under which study samples will be collected, stored, and processed. Assessment should include bench-top stability, refrigerator stability, whole-blood stability, freeze-thaw stability, and long-term freezer stability. Stability samples can be prepared by spiking the analyte reference at high and low concentrations into the sample matrix. [Pg.621]
