Webcellulose membrane. Stable process pressures and flow conditions indicate absence of plugging and suitability of cassette design. No Protein Loss Samples of composite permeate from each process run were analyzed for protein using the biuret method. No protein loss was detected in the permeate, indicating greater than 99.9% protein yield. Web1 de mar. de 2010 · Figure 1: This graph shows the overall Normalized Permeate Flow for Train 4, along with a line indicating a necessary cleaning. Since the graph of the NPF has not dropped below the cleaning line, it can be surmised that this train does not need to be cleaned based on flow at this time.
