Description

Application

Micro particles based on melamine resin, carboxylate-modified, FITC-markedsize: 1 μm is used for equipment particle size calibration with fluorescence detection.

Analysis Note

For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.

Other Notes

Fluorescent marker for macrostructures, e.g. microtubules[1]; Aldehyde modification for coupling with amines[2]

A strategy for the chemical synthesis of nanostructures.

W T Müller et al.

Science (New York, N.Y.), 268(5208), 272-273 (1995-04-14)

Highly localized chemical catalysis was carried out on the surface groups of a self-assembled monolayer with a scanning probe device. With the use of a platinum-coated atomic force microscope tip, the terminal azide groups of the monolayer were catalytically hydrogenated

Localization of an exchangeable GTP binding site at the plus end of microtubules.

T J Mitchison

Science (New York, N.Y.), 261(5124), 1044-1047 (1993-08-20)

Microtubule polarity arises from the head-to-tail orientation of alpha-beta tubulin heterodimers in the microtubule lattice. The identity of the polypeptide at each end of the microtubule is unknown, but structural models predict that the beta-tubulin end contains an exchangeable guanosine
