Describe briefly the following:
Downstream processing
Advertisements
उत्तर
The product prepared by biotechnology is subjected to several processes before it is sent to the market. These processes include separation and purification and are collectively called downstream processing. The product is formulated with appropriate preservatives. In the case of drugs, such formulations are put through clinical trials. Every product also requires specific quality control tests. Downstream processing and quality control tests vary for different products.
