产品描述
Background:
Streptavidin Magnetic Beads
are ideal for numerous applications, including purification of proteins and
nucleic acids, protein interaction studies, immunoprecipitation, immunoassays,
phage display, biopanning, drug screening and cell isolation.
Add the beads to
a sample containing biotinylated molecules, e.g. peptides, proteins,
antibodies, oligonucleotides, DNA/RNA. During a short incubation, the
biotinylated molecule will bind to the beads. Separate the molecule-bead
capture, washing, and detection can be optimized for manual or automated use.
With indirect capture, mix the biotinylated molecule with the sample to capture
the molecule target complex before adding the beads. Indirect target capture is
an advantage when molecule-target kinetics are slow, affinity is weak, molecule
concentration is low, or molecule-target
binding requires optimal molecule orientation and true liquid-phase
kinetics.
Streptavidin is
covalently coupled to a magnetic particle. Streptavidin Magnetic Beads can be
separated from solution using our 6-Tube Magnetic Separation Rack or 12-Tube
Magnetic Separation Rack which concentrates the beads to the side of the tube
instead of the bottom. This eliminates centrifugation steps, minimizes sample
loss, increases washing efficiency, and saves time.
Specificity：Binding to biotinylated molecules, e.g.
nucleic acids, peptides, proteins, antibodies.
Tested applications: For
coupling of proteins, antibodies, peptides and other molecules. Optimal amount
should be determined by the end user.
