WebLyophilization Technologies is a dehydration process that takes place after a product has been frozen. Lyophilization is popular in life sciences because lyophilized reagents and assays have many benefits including ease of use and reduced total cost. Lyophilized reagents ship at ambient temperature, reduce storage and shipping costs.
Web2.11 Prozone (or “Hook”) Effect. The Prozone or hook effect is observed when a very high amount of an analyte is present in the sample but the observed value is falsely lowered. This type of interference is observed more commonly in sandwich assays. The mechanism of this significant negative interference is the capability of a high level of ... Web15 oct. 2016 · Only small reductions in RNA integrity were identified in lyophilized, stored sample compared to that of flash-frozen or lyophilized sample not subjected to storage. Reductions in RNA integrity were most profound in ovary tissue, which has a notably higher lipid content (∼35% of dry weight) than liver (∼17%) or spleen (∼15%).
