Serum, as a good assistant in cell culture, plays an important role in the growth process of cells. The quality of serum directly affects the results of cell culture. If there is too much precipitation, it will inevitably cause concern. So, how do we avoid precipitation in   petg media bottles ? First of all, we should have a correct understanding of precipitation. When turbid and flocculent substances are found after thawing the serum, there is no need to panic. This is a normal phenomenon. Common deposits include fibrin, calcium phosphate, cholesterol, fatty acid esters, and some proteins. The amount of serum sedimentation is not directly proportional to the quality of the serum. If serum precipitation occurs, don’t worry. Usually, centrifuge at 400-600g for 5 minutes to remove large particle precipitation, and then use the supernatant. PETG Media Bottles Of course, if you still feel uneasy, you can take the following measures to avoid precipitation in the petg media bottles as m...

  Serum is a nutrient required for cell culture, and plays an important role in maintaining osmotic pressure, promoting cell attachment and spreading, and maintaining logarithmic growth of cells. The serum is stored in a special   media bottle , but if the quality of the bottle is not up to standard, it will directly affect the quality of the serum. In general, the quality of serum depends on two factors: one is the object of sampling, and the other is the process of sampling. Animals used for sampling should be healthy and disease-free and within the specified number of days of birth. The sampling process should be strictly in accordance with the operating procedures, and the prepared serum should undergo strict quality identification. Requirements in the "Procedures for the Production of Biological Products Using Animal Cells in Vitro Culture" published by WHO: 1. Bovine serum must be from a herd or country that is documented to be free of BSE. and should have an appropriat...
