PurSolutions launches biotin-labeled tubulin

PurSolutions, LLC added tubulin conjugated with Biotin-XX to its product line to cater to biophysicists and nanotechnologists studying self-assembling polymers. Tubulin functionalized with biotin permits immobilization of microtubules on streptavidin-coated solid surfaces such as glass coverslips and beads. As such, biotinylated tubulin is useful in a number of applications including in vitro optical traps, molecular tweezers, fluorescent imaging systems, single molecule kinesin motor assays, tubulin affinity columns, and nanoscale biohybrid devices.
