These latex beads have a mean particle size of 0.03 um and tend to remain well suspended over time. Should settling occur, gently mixing or vortexing to resuspend is recommended. After dilution, gentle vortexing is sufficient to obtain a homogeneous suspension. Ultrasonication or vigorous agitation is not recommended. The beads contain approximately 0.5% anionic surfactant to aid dispersion; surfactant loss may promote particle clustering. Please see the links below to review additional general information regarding usage and handling of latex beads:

Application
Carboxylate-modified polystyrene latex beads have been used to collect morphofunctional data about the immune systems of Carabus lefebvrei, a helicophagous Italian endemic ground beetle often used as an indicator of the habitat quality of the Apennines mountain forests. Carboxylate-modified polystyrene latex beads have also been used to inform comparative studies on immunity defense mechanisms of adults and larvae of the coleopteran Cetonischema aeruginosa and to investigate the phagocytic activity of cultured rat thyroid cells.

What is the concentration of product L5155?
1 answer-
This product has a solid content (bead content) of 2.5% (w/w). The product density is reported on a lot specific basis with a range of 1.04 - 1.06 g/mL. The bead number can be calculated and then diluted according to the required number. The formula for determining the number of beads in the samples is: Bead number = (6.03 x 10^10) x (percent solids) / 3.30 x (bead diameter).
