Product nameProtein A Resin - Amintra
Protein A Resin - Amintra® (ab270308) is is an affinity chromatography medium designed for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and cell culture media. The recombinant protein A ligand is coupled to highly cross-linked 4% agarose resin. The coupling is optimized to give high binding capacity for immunoglobulins. The static binding capacity of Protein A Resin - Amintra® is greater than 40 mg human IgG per mL settled resin. The dynamic binding capacity varies depending on several factors such as the target antibody, flow rate during binding, etc.
This product is manufactured by Expedeon, an Abcam company, and was previously called Amintra® Protein A Resin. Expedeon product codes APA0005 (5 mL Medium), APA0025 (25 mL Medium) and APA0100 (100 mL Medium) are the same as the current sizes: 5 mL, 25 mL, and 100 mL, respectively.
