摘要: The invention is a high-throughput voltage screening crystallographic device and methodology that uses multiple micro wells and electric circuits capable of assaying different crystallization condition for the same or different proteins of interest at the same of different voltages under a humidity and temperature controlled environment. The protein is solubilized in a lipid matrix similar to the lipid composition of the protein in the native environment to ensure stability of the protein during crystallization. The invention provides a system and method where the protein is transferred to a lipid matrix that holds a resting membrane potential, which reduces the degree of conformational freedom of the protein. The invention overcomes the majority of the difficulties associated with vapor diffusion techniques and essentially reconstitutes the protein in its native lipid environment under “cuasi” physiological conditions.

摘要: Apparatus and methods are provided relating to evaporation of solvents from samples and to prolonging the time taken to carry out an evaporation procedure. A cap for engaging with an open end of a sample container comprises an engaging surface for engaging with the open end, and a body portion which extends over the open end. The body portion is preformed to define an opening which provides a fluid pathway between the open end of the container and the surroundings of the container, such that the cap impedes vapor flow from a sample in the container to the surroundings of the container. A holder for receiving a plurality of such caps is also provided and a method of evaporating a solvent from a sample in a sample container is described.

摘要: Microfluidic structures and methods for manipulating fluids and reactions are provided. Such structures and methods may involve positioning fluid samples, e.g., in the form of droplets, in a carrier fluid (e.g., an oil, which may be immiscible with the fluid sample) in predetermined regions in a microfluidic network. In some embodiments, positioning of the droplets can take place in the order in which they are introduced into the microfluidic network (e.g., sequentially) without significant physical contact between the droplets. Because of the little or no contact between the droplets, there may be little or no coalescence between the droplets. Accordingly, in some such embodiments, surfactants are not required in either the fluid sample or the carrier fluid to prevent coalescence of the droplets. Structures and methods described herein also enable droplets to be removed sequentially from the predetermined regions.
