General description

The Direct Detect infrared (IR)-based quantification system is an innovative combination of software-controlled instrumentation and EMD Millipore Corporation’s advanced membrane technology, optimized for the detection and quantification of proteins. Biomolecules are applied directly to a card-based hydrophilic polytetrafluoroethylene (PTFE) membrane that is transparent in most of the infrared spectral region. The Direct Detect system measures amide bonds in protein chains, accurately quantifying an intrinsic component of every protein without relying on amino acid composition, dye binding properties, or redox potential. Protein concentrations from 0.2 to 5 mg/mL can accurately be determined from a minimal sample volume (2 μL) without bio- or immuno-chemical staining. Sample analysis takes only minutes and in most cases can be performed directly from the buffered or native solution.

Protocolos

Rapid Antibody Concentration with Amicon® Ultra Centrifugal Filters

Purification protocols for immunoglobulins generally include affinity binding to Protein A or G chromatography media, washing unbound proteins, and eluting with a low pH buffer.

Concentración rápida de anticuerpos con los filtros para centrífuga Amicon® Ultra

Los protocolos de purificación de las inmunoglobulinas suelen incluir la unión por afinidad a los medios cromatográficos de proteína A o G, el lavado de las proteínas no adheridas y la elusión con un tampón de pH bajo.

Nuestro equipo de científicos tiene experiencia en todas las áreas de investigación: Ciencias de la vida, Ciencia de los materiales, Síntesis química, Cromatografía, Analítica y muchas otras.
