Biological Samples
CAUTION:
Human and animal samples may contain biohazardous
infectious agents. Where exposure to potentially biohazardous
material—including aerosol—exists, follow appropriate biosafety
procedures and use personal protective equipment such as
gloves, gowns, laboratory coats, face shields, or mask and eye
protection. Use ventilation devices. Observe all local, state, and
federal biohazard handling regulations when disposing of
biohazardous waste material.
Dilute concentrated biological samples, such as plasma or serum, at least 1:5 with reagents
as part of assay setup or as a final dilution step to reduce the chance of system clogs. If you
are running a MagPlex
®
kit, follow the dilution instructions in the kit’s product insert.
Bead (Microsphere) Handling
MagPlex beads come in various configurations. To reduce foaming and surface precipitation,
avoid agitating the beads until you are ready to vortex and use them. The beads will settle
and must be resuspended by vortexing before use. In addition:
• Multiple pipetting from the original container may affect bead concentrations.
• Protect MagPlex beads from light at all times to prevent photobleaching. Photobleaching
effects are cumulative. To maintain the integrity of the beads, minimize their exposure to
light during your development and manufacturing phases.
• Store MagPlex beads at 2°- 8°C.
