The Streptavidin Coated Beads, based on superparamagnetic or non-magnetic beads covalently coated with streptavidin, are designed to bind a variety of biotinylated molecules in immunoprecipitation, immunoassay(ELISA), cell sorting, protein interaction studies, protein/DNA hybridization reaction or even DNA sequencing application.

Product Introduction
(SA-Biotin) system has extremely high binding affinity (Kd=10^-15), It has a wide range of applications in the biological field.  Sunlong Biotech™  Streptavidin covalently connects the SA to the solid carrier surface by using the patented protein coupling technique of Sunlong, which can efficiently bind the ligands such as biotinylated antibodies, nucleic acids, proteins etc. The product adopts superparamagnetic microspheres with uniform size and regular morphology, which facilitates the rapid and convenient capture of target molecules and the realization of magnetic separation. This product can be equipped with automation equipment for high flux operation.

Note
1. Avoid freezing magnetic beads and other operations.
2. In order to reduce the loss of magnetic beads, the time of magnetic separation should be no less than 1 min.
3. The magnetic beads should be fully shake and suspended evenly before the magnetic beads are removed from the magnetic storage tube. Bubbles should be avoided during operation.
4. It is recommended to use a good pipette suction head and a reaction tube to avoid losses due to adhesion of magnetic beads and solution.
5. The size of biotinylated molecules affects the magnetic bead loading. Users need to determine the load of magnetic beads to specific biotinylated molecules according to the experiment.
6. The amount of biotinylated molecules should be 1~2 times of the magnetic beads, in order to saturate the magnetic beads.
7. This product is for research and use only.
