Gold Nanohelices - Chirality Tomography Markers Product information: The Gold Nanohelices (L,R) are chiral nanoscale markers especially suited for 3D Tomography (only nanohelices in buffer) / Electron Microscopy (EM) / CryoEM. Our chiral markers show pure chirality (L or R), which can easily be detected with EM due to the high contrast and the precise arrangement of the gold nanoparticles. The Gold Nanohelices (L,R) are fabricated with the DNA origami technique where gold nanoparticles (10 nm) are arranged into nanoscale helices (helical pitch 57 nm; length 110 nm; diameter 34 nm). On TEM grid: The samples are delivered ready to use on a dried TEM grid. To increase the helix effect they are magnified by silver enhancement. For shipping the samples are stored in parafilm covered plastic wells. Durability is 6 month. In buffer: The Nanohelices are delivered in buffer (1x TAE, 11 mM MgCl2). The sample size is ~ 30 μL which is enough for the preparation of more than 10 TEM grids. Shipping will be carried out in a cooled thermo-box. Keeping suitable storage conditions (dark, 4 °C) the durability is 3 month.

Nanorulers from the GATTA-PAINT series are the ideal resolution rulers for any type of localization based super-resolution microscopy. Due to the mechanism for providing the blink kinetics which is based on the DNA PAINT technology the samples are nearly free of photo bleaching. In addition the design containing three emitting points allows the acquisition of very eye-catching images. We offer for the GATTA-PAINT nanorulers the mark-to-mark distances in the sizes 40 nm and 80 nm. Both sizes are available in the colors red (ATTO 655), green (ATTO 542) or yellow (Cy3B) as well as in the color combination red/green (ATTO 655 & ATTO 542) or red/yellow (ATTO 655 & ATTO Cy3B). product properties of GATTA-PAINT 80 nm Nanoruler - PAINT 80R: Color red; Available fluorophores ATTO 655; Recommended laser source 625 - 665 nm; Surface density ≈ 1/µm²; Distance 2x 80 nm; Level Beginner; Price 365,-€ - PAINT 80Y: Color yellow; Available fluorophores Cy3B; Recommended laser source 560 – 590 nm; Surface density ≈ 1/µm²; Distance 2x 80 nm; Level Beginner; Price 365,-€ - PAINT 80G: Color green; Available fluorophores ATTO 542; Recommended laser source 530 - 560 nm; Surface density ≈ 1/µm²; Distance 2x 80 nm; Level Beginner; Price 365,-€ product properties of GATTA-PAINT 40 nm Nanoruler - PAINT 40R: Color red; Available fluorophores ATTO 655; Recommended laser source 625 - 665 nm; Surface density ≈ 1/µm²; Distance 2x 40 nm; Level Advanced; Price 365,-€ - PAINT 40Y: Color yellow; Available fluorophores Cy3B; Recommended laser source 560 – 590 nm; Surface density ≈ 1/µm²; Distance 2x 40 nm; Level Advanced; Price 365,-€ - PAINT 40G: Color green; Available fluorophores ATTO 542; Recommended laser source 530 - 560 nm; Surface density ≈ 1/µm²; Distance 2x 40 nm; Level Advanced; Price 365,-€ Beginner: Samples to check the basic functions of your microscope.
