Polystyrene beads are available in several formats - unmodified, carboxyl-modified, or amine-modified - as well as various colors and numberous sizes. This particular product is an amine-modified bead containing a blue fluorescent dye. See the image below to review the basic structure. This is a surface modification that allows for the attachment of certain ligands such as polypeptides via the carboxyl-terminus. The dyes are embedded in the polystyrene bead during the manufacturing process. These are not bound to the surface of the bead.

Alkalmazás
Carboxylate-modified polystyrene latex beads (fluorescent orange) have been used to block phagocytosis by hemocytes in Drosophila.[1] It has also been used to assess the uptake of latex beads by antigen presenting cells from porcine respiratory system.[2]
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 does "λex ~520 nm" mean? In particular, I do not understand the meaning of "~". Is it possible to excite with excitation wavelengths from 430 to 510 nm? 「λex ～520 nm」とはどういう意味ですか？ 特に「～」の意味がわかりません。 430～510nmの励起波長で励起できるのですか？
1 answer-
Product L5530 is a fluorescent product having λex ~520 nm; λem ~540 nm, where λex ~520 nm means excitation at 520nm and λem ~540 nm means emission at 540nm. The spectra is quite tight and hence it will be important to set the filters accordingly. "~" means "about/around" in this aspect, where if λex is 520 nm, +/- 5 to 10 nm difference in the wavelength should be alright.
Generally, a range of 430-510nm ex/em is not suitable for green fluorochomes. The 430 nm wavelength is too early for excitation and is not recommended for this product.Helpful?
