The present invention relates to a novel method for the isolation or purification of immunoglobulins (a special class of proteins) from a solution containing immunoglobulins, e.g. hybridoma cell culture supernatants, animal plasma or sera, or colostrum. The method includes the use of a minimum of salts, such as lyotropic salts, in the binding process and preferably also the use of small amounts of organic solvents in the elution process. The solid phase matrices, preferably epichlorohydrin activiated agarose matricees, are functionalised with mono- or bicyclic aromatic or heteroaromatic ligands (molecular weight: at the most 500 Dalton) which, preferably, comprises an acidic substituent, e.g. a carboxylic acid. The matrices utilised show excellent properties in a “Standard Immunoglobulin Binding Test” and in a “Monoclonal Antibody Array Binding Test” with respect to binding efficiency and purity, and are stable in 1M NaOH.

Design optimization methods can be used to design concrete mixtures having optimized properties, including desired strength and slump at minimal cost. The design optimization methods use a computer-implemented process that is able to design and virtually “test” millions of hypothetical concrete compositions using mathematical algorithms that interrelate a number of variables that affect strength, slump, cost and other desired features. The design optimization procedure utilizes a constant K (or K factor) within Feret's strength equation that varies (e.g., logarithmically) with concrete strength for any given set of raw material inputs and processing equipment. That means that the binding efficiency or effectiveness of hydraulic cement increases with increasing concentration so long as the concrete remains optimized. The knowledge of how the K factor varies with binding efficiency and strength is a powerful tool that can be applied in multiple circumstances. A concrete manufacturing process may include accurately measuring the raw materials to minimize variation between predicted and actual strength, as well as carefully controlling water content throughout the manufacturing and delivery process.

The invention provides methods and devices for detecting the presence of one or more target analytes in a sample employing a channel having affixed therein one or more binding partners for each target analyte. Assays are carried out by transporting the sample through the channel to each successive binding partner so that target analyte present in said sample binds to the corresponding binding partner. The sample is then transported beyond the binding partner(s), followed by detection of any target analyte bound to each binding partner. In one embodiment, binding efficiency is increased by the use of segmented transport, wherein a first bolus or bubble of a fluid that is immiscible with the sample precedes the sample during transport and a second bolus or bubble of a fluid that is immiscible with the sample follows the sample. Many configurations are possible for the device of the invention. A preferred device includes: a substrate with a channel formed in its surface, and a cover element that overlies and seals the channel. Binding partner(s) are affixed to the surface of the cover element facing the channel lumen.
