Making Diluted Solutions of MicroSpheres
Revision as of 14:02, 24 November 2014 by Wikiuser
Procedure - From liquid with ~ 10% solids
- Shake microsphere bottle to evenly disperse the particles.
- Remove 100ul of cloudy white microsphere solution and dilute with 20ml of deionized water (200:1 dilution).
- Bovine Serum Albumin (BSA) and (for non-biological particles) 1% polyethylene glycol can be added as anti-stick agents.
- For biological particles BSA and Phosphate-Buffered Saline (PBS - 0.8% NaCl, 0.02% KCL, 0.02M PO4, pH 7.3 (percentage by weight)) can be used as anti-stick agents.
Students: If this recipe is inadequate (too many or too few particles) please revise.
