Dynabeads® M-270 Carboxylic Acid These are hydrophilic Dynabeads® (2.8 µm) with carboxylic acid groups. These surface groups allow covalent amide bond formation to proteins/peptides via primary amino- or sulphydryl groups. ■Immediate and gentle coupling at low temperature and neutral to low pH ■Activation through carbodiimide is required ■Alternative reactive groups can be introduced by using commercially available cross-linkers Applications: Ideal for isolation of small components such as proteins and peptides. Immobilization of labile proteins/peptides and N-terminal coupling of peptides. Low non-specific binding of nucleic acids. Concentration: 2 × 109 beads / ml Surface Functionality: Carboxylic Acid Form: Beads in Suspension Shelf Life: 36 months Product Size: 2 mL Elution Volume - min: 5 µl Sample Type (Specific): Any Sample Type High Throughput Compatibility: High Throughput-Compatible Shipping Condition: Room Temperature Regulatory Statement: For Research Use Only.
