Polysciences Bead Solution ...............................................
Polysciences Bead Solution is a ready-to-use aqueous suspending solution for the
dilution and/or storage of your uncoated plain, dyed or functionalized polymer
microspheres (both carboxylated or aminated). An antimicrobial agent deters
microbial contamination, and stabilizers promote suspension dispersity, peace of
mind, and harmonious accord in the laboratory.
Polysciences Bead Storage Buffers
Ready-to-use buffers that are available in two pH levels (7.4 and 8.5).

Accessory Reagents
DEPC-Carbodiimide (EDAC) HO6bf ............................................
EDAC is a zero-length crosslinker that is routinely used for the covalent binding of amine-containing
ligands to carboxylated microspheres.
Glutaraldehyde, EM Grade, 25% HOV6d .......................................
Homobifunctional linker that is suitable for binding amine-containing ligands to amine-modified
beads. We supply EM (electron microscopy) grade glutaraldehyde in ampoules to ensure highest
activity. Each ampoule is fitted with an ampoule cracker for added safety.
Surfactants
Triton ® X-100 Nonionic Surfactant HV5g .......................................
Nonionic surfactant. It is often used in the storage buffers of coated bead suspensions. Very low
concentrations may be used in wash or binding buffers if needed (e.g. 0.0005%).
Tween ® 20 Nonionic Surfactant A2g ...........................................
Nonionic surfactant. It is often used in the storage buffers of coated bead suspensions. Very low
concentrations may be used in wash or binding buffers if needed (e.g. 0.0005%).
Sodium Dodecyl Sulfate (SDS) Anionic Surfactant HO3g .........................
Anionic surfactant, which will decrease polymer bead hydrophobicity and can additionally participate
in charge stabilization of the suspension. SDS is a more rigorous surfactant that is commonly
used in uncoated polymer bead preparations.
