| Product Description | GenScript Streptavidin MagBeads are super paramagnetic beads of approximately 45-100 μm in diameter, covalently coated with highly purified streptavidin. These magnetic beads are composed of magnetite core encapsulated by agarose. The magnetic beads have streptavidin as its surface protein which is 53kDa. in size having four binding site per molecule. These beads have pH stability of 2 to 14 (short term); 3 to 13 (long term). The beads are supplied as 25% slurry in phosphate buffered saline (PBS), pH 7.4, containing 20% ethanol. |
