The present invention describes methods and processes for the production of proteins, particularly glycoproteins, by animal cell or mammalian cell culture, illustratively, but not limited to, fed-batch cell cultures. The methods comprise feeding the cells with D-galactose, preferably with feed medium containing D-galactose, preferably daily, to sustain a sialylation effective level of D-galactose in the culture for its duration, thus increasing sialylation of the produced proteins.

Supplementation of the cultures with D-galactose, preferably in a feed medium, to sustain galactose at sialylation effective levels in the cultures until the end of a culture run reverses a decline in sialylation that accompanies culture scale up, and is advantageous for large scale culturing processes.

If the two displayed temperatures are aligned, then the refrigerant charge is optimized, and if they are not aligned, the system is undercharged or overcharged.

Scale deposition on a heat transfer surface in a liquid system such as a heat exchanger is estimated by directing of small portion of the liquid flow through a test cell, consisting of a sensor positioned on and projecting through a conduit wall. The sensor consists of a conductive block containing a heater and having a heated wetted test surface that is flush with the inside of the conduit wall and in contact with the flow through the conduit. Within the conductive block are two temperature sensors which are at different distances from the heated wetted test surface and the heater. The periphery of the apparatus is designed to reduce heat flow through the periphery and allow greater heat flow through the heated wetted test surface. By comparing the temperature differential between the two temperature sensors to the differential when no scale is present, the presence of and amount of scale can be determined, based on reduced heat transfer through the heated wetted surface caused by the accumulated scale. The change in the temperature differential is directly proportional to the scale thickness for a given type of scale. When the thickness of the scale is determined by another means, the nature of the scale can be implied. The sensitivity of the measurement can be adjusted to accommodate a very wide range of bulk liquid or ambient temperature via adjustment of the heat flux through the provided secondary heat flux path.
