The present invention provides, in part, methods for recombinantly expressing proteins at a high level along with cell culture media for doing the same.

A method of tracking and predicting the spread of micro-organisms in an environment relies on the optical detection of the growth of micro-organisms within an analyte containing a growth medium for the micro-organism(s) to be detected. Standardization of the containers and growth medium for each micro-organism allows rapid detection of the growth pattern of particular organisms and the implementation of a regime of remote self-reporting of results from portable incubator units (1201) in the field which include a memory (1206) to store the results, a GPS unit (1204) to provide location information and a transmitter (1203) to send the results to a central plotting organization allowing rapid tracking and prediction of the spread of environmentally borne organisms.

The invention provides an improved lead-acid cell medium dense polar plate separating and brushing integrated machine. The machine sequentially comprises a feeding mechanism used for conveying two connected polar plates, a polar plate side frame brushing mechanism used for cleaning the side edges of the polar plates conveyed by the feeding mechanism, a lug brushing mechanism used for cleaning lugs of the polar plates output by the feeding mechanism, a separating mechanism used for separating the two connected polar plates, a polar plate arranging mechanism used for arranging the separated polar plates, a polar plate overturning mechanism used for overturning the arranged polar plates, and a polar plate separation side edge brushing mechanism used for cleaning the separation sides of the overturned polar plates. By additionally arranging the polar plate side frame brushing mechanism between the feeding process and the lug brushing process, the upper frame and lower frame of each polar plate can be cleaned. By additionally arranging the polar plate overturning mechanism, the separation sides of the polar plates are well cleaned, and lead powder can be completely removed.

The invention belongs to the technical field of cell culture, and particularly relates to a knockout serum replacement for cell culture and a preparation method thereof, a knockout serum replacement composition for cell culture and a cell culture medium. The knockout serum replacement for cell culture comprises, by weight, water, 18.5-67 parts of amino acid, 200-815 parts of protein, 62.5-252 parts of inorganic salt, 1.0-3.8 parts of ethanol amine, 50-200.0 parts of sodium pyruvate, 1.25-5.0 parts of ascorbyl phosphate, 0.5-2.0 parts of glutathione and 5.0-20 parts of insulin. The knockout serum replacement for cell culture can be added into any one cell culture medium, the adding amount of serum is reduced, and therefore, the cost is saved. The knockout serum replacement for cell cultureis suitable for protein recombination, vaccine production and other kinds of cell culture, and high in universality.
