SoftLink Resin is a rigid, methacrylate polymeric gel filtration matrix, functionalized with covalently bound, monomeric avidin. Monomeric avidin allows both the specificity of capture and the mildness of release appropriate for the purification of sensitive biological materials.

  • Binds 20–40nmol of biotinylated protein per milliliter of resin
  • Retains biotin binding ability following exposure to a wide range of pH, low or high ionic strength solutions, 6M guanidine, and 1% SDS
  • Regenerates at least 10 times without loss of binding capacity
  • Supports high flowrates (300cm/hr.) and centrifugal forces (1500 × g) in batch applications
  • Ideal for the isolation and purification of biotinylated antibodies and other proteins

For research use only. Not for diagnostic or therapeutic use.
