Preparation Lyophilized purified Ig fraction
Applications This reagent has been specifically designed for the detection of biotinylated biological probes such as antibodies or cytokines in Flow Cytometry or Immunhistochemisty.
The maximum amount of reagent to stain 1 x 10e6 cells in Flow Cytometry is approximately 1.0 µg of Streptavdin RPE. Lesser amounts of reagent may be sufficient for staining.
As a general guideline dilutions of 1/100-1/250 should be suitable for most applications.
Recommended Dilutions:
Flow Cytometry: 1/100-1/250.
IF Microscopy: 1/100-1/250
Storage Prior to reconstitution store at 2-8°C.
Following reconstitution store the antibody undiluted at 2-8°C for one month
or (in aliquots) at -20°C for longer.
Avoid repeated freezing and thawing.
Stability Shelf life: one year from despatch.
