Example 2

A P-2000 CO₂laser puller (Sutter Instrument, Novato, Calif.) was used to pull quartz capillaries (Q100-70-7.5, Sutter Instrument, Novato, Calif.) to inner diameters that range from 20 nm to 35 nm. All capillaries were cleaned with piranha solution (3:1 v/v H₂SO₄:30% H₂O₂) prior to pulling. After fabrication, all pipettes were imaged using scanning electron microscopy and scanning transmission electron microscopy (Quanta FEG 600F, FEI, Hillsboro, Oreg.). Pipettes were back-filled with PBS using a MicroFil needle (World Precision Instruments, Sarasota, Fla.) and centrifuged before use in experiments.

Quartz Glass Pipette Fabrication

Check if the same lab product or an alternative is used in the 5 most similar protocols

Pipettes used in the experiments were pulled from quartz glass capillaries (Q100-70-7.5, Sutter Instrument, Novato, CA, USA) with a CO₂-laser puller (P2000, Sutter Instrument, Novato, CA, USA). Typical pulling parameters used in the experiment were heat = 690, Fil = 4, Vel = 45, Del = 160, and Pul = 190. Pipettes were then characterized by scanning electron microscopy (SEM; FEI Quanta-FEG, Hillsboro, OR). Electron micrographs are shown in Section SI-1. The typical inner and outer radii of pipettes are 50 and 70 nm, respectively, with a half-cone angle of ~7.5°.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
