The morphology and layer height were analyzed by nanoscale AFM measurements. The graphene oxide sample (~1 μg mL−1) was deposited on a freshly cleaved mica surface, incubated for a couple of minutes, and then gently dried under a nitrogen stream. AFM images were obtained in tapping mode using a Nanoscope IV PicoForce Multimode AFM (Bruker, Santa Barbara, CA) equipped with an E-scanner and a rectangular-shaped silicon cantilever with a 42 N/m spring constant and a resonant frequency of ~300 kHz in an ambient environment.53 (link), 54 (link)

Nanoscale AFM imaging was employed to investigate the dynamic forms polymers due to allosteric regulation of hACC2 by citrate. The Δ148aa-hACC2 was incubated with or without 15 mM citrate for 20 min at 37 °C. The resultant mixtures were placed on the freshly cleaved mica surface and incubated for several hours in a moisture chamber. After washing with water and drying under nitrogen, the samples were subjected to tapping mode AFM imaging on the Nanoscope IV PicoForce Multimode AFM, equipped with an E-scanner and a rectangular-shaped silicon cantilever (Bruker, Madison, WI, USA) with a 42-N/m spring constant and a resonant frequency of ~300 kHz at ambient environment (Park et al. 2008b (link); Park and Terzic 2010 (link)). Images (512 × 512 pixels/image) were collected from each sample with maximum image size of 5 × 5 μm and analyzed using the Nanoscope Version 6.13 software (Bruker).

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.
