Abstract: A process for continuous preparation of halogenated alkoxyethane of general formula XCIHC—CF2OR, where X is —Cl or —F and OR is C1-4 alkoxy, the process comprising a step of introducing in a plate reactor reaction components comprising (i) a compound of general formula XCIHC—CYF2, where each of X and Y is independently —Cl or —F, (ii) a base, and (iii) a C1-4 alkanol, wherein (a) the plate reactor comprises a fluidic module defining one or more fluidic path(s) through which the reaction components flow as a reaction mixture, and (b) the halogenated alkoxyethane is formed at least upon the reaction components mixing, with the so formed halogenated alkoxyethane flowing out of the plate reactor in a reactor effluent, and (c) the base is one that forms a salt soluble in the alkanol during formation of the halogenated alkoxyethane.

Abstract: The compositions and methods of the present invention are based, in part, on our discovery that an effector function mediated by an Fc-containing polypeptide can be altered by modifying one or more amino acid residues within the polypeptide (by, for example, electrostatic optimization). The polypeptides that can be generated according to the methods of the invention are highly variable, and they can include antibodies and fusion proteins that contain an Fc region or a biologically active portion thereof.

Abstract: The present invention relates to improved methods for producing biologically active truncated APRIL ligand polypeptides and analogs thereof. The invention further relates to truncated APRIL ligand polypeptides and analogs thereof that retain a high biological activity and may be isolated in high yields, as well as the nucleotide sequences that encode the truncated APRIL ligand polypeptides and analogs thereof. The invention also relates to compositions of the biologically active truncated APRIL ligand polypeptides and analogs thereof. The invention further relates to the use of the biologically active truncated APRIL ligand polypeptides and analogs thereof in promoting cell proliferation.

Abstract: Methods for improving the sensitivity of hybridization assays which reduce non-specific binding (NSB) and non-specific hybridization (NSH) are disclosed. The methods include a washing method utilizing tetraalkylammonium salts at high temperatures, and release methods in which a probe-target complex is released from a solid support and recaptured. Use of both the washing and release methods results in substantial reduction in NSB and NSH without performing several rounds of release and recapture of the target nucleic acids.
