摘要:
Methods are provided for the synthesis and secretion of recombinant hetero-multimeric proteins in mating competent yeast. A first expression vector is transformed into a first haploid cell; and a second expression vector is transformed into a second haploid cell. The transformed haploid cells, each individually synthesizing a non-identical polypeptide, are identified and then genetically crossed or fused. The resulting diploid strains are utilized to produce and secrete fully assembled and biologically functional hetero-multimeric protein.

Compositions and methods including Amodiaquine (AQ) or N-Desethy Amodiaquine (DEAQ) are provided for treating, inhibiting, or preventing cathepsin B dependent pathogens and toxins in a host cell or infected subject. Compositions and methods also include AQ or DEAQ in combination with an antibiotic for more effective clearance of the pathogen and/or toxins.
摘要:
Oscillating angularly rotating a container containing a material may cause the material to be separate. Denser or heavier material may unexpectedly tend to collected relatively close to the axis of rotation, while less dense or light material may tend to collect relatively away from the axis of rotation. Oscillation along an arcuate path provides high lysing efficiency. Alternatively, a micromotor may drive an impeller removably received in a container. Lysing may be implemented in batch mode, flow-through stop or semi-batch mode, or flow-through continuous mode. Lysing particulate material may exceed material to be lysed or lysed material and/or air may be essentially eliminated from a chamber to increase lysing efficiency.
摘要:
A valve has a generally hollow core with one open end and one closed end, and at least one side port in a sidewall of the core. The valve also includes a sleeve that fits over the core and covers the side port(s). The cracking pressure of the valve is tunable by varying the parameters of the sleeve.

摘要:
In accordance with the invention, isolated nucleic acids, expression methods, host cells, expression vectors, and DNA constructs for producing proteins, and proteins produced using the expression methods are described. More particularly, nucleic acids isolated from Pichia pastoris wherein the nucleic acids have promoter activity are described. The invention also relates to expression methods, host cells, expression vectors, and DNA constructs, for using the Pichia pastoris promoters to produce proteins, and to the proteins produced using the expression methods.
