Glass Beads - Functionalized
These are high surface area soda lime glass beads which have been functionalized by reaction with
the appropriate organosilane. Proteins, peptides, dyes and other compounds can be coupled to
the amine-functional beads as supplied and the glycidyl-functional beads after periodate oxidation.
Additional sizes are available on a custom basis.

Ragweed Pollen A4g
Ragweed pollen is a short type, botanical named Ambrosia artemisiifolia. It is collected under a
vacuum method and exceeds identity and purity by microscopic identification. Contains less than
0.1% contamination with foreign pollens or molds. Plant parts do not exceed 5% for anemophilous
(wind pollinated) pollen or 12% for entomophilous (insect pollinated) pollen.
