Descrizione generale

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.

Articoli

Direct Detect® Infrared Spectrometer for Total Protein Quantitation

Learn how total protein quantitation with an infrared spectrometer may be a more accurate and universal alternative to Bradford, BCA, or UV-based methods.

Protocolli

Concentrazione rapida di anticorpi con i filtri centrifughi Amicon® Ultra

I protocolli di purificazione delle immunoglobuline generalmente includono il binding a una resina per cromatografia di affinità funzionalizzata con proteina A o G, il lavaggio delle proteine non legate e l’eluizione con un tampone a basso pH.

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.

Il team dei nostri ricercatori vanta grande esperienza in tutte le aree della ricerca quali Life Science, scienza dei materiali, sintesi chimica, cromatografia, discipline analitiche, ecc..
