Poly(ethylene glycol) diacrylate (PEGDA, MW = 575 Da), N-vinyl pyrrolidone (NVP), potassium monobasic phosphate (phosphate), sodium hexametaphosphate (polyphosphate, (NaPO3)n MW = 101.9618*n)), potassium persulfate (KPS), sorbitan monooleate (SPAN80), PEG (20) sorbitan monolaurate (TWEEN20), cyclohexane, acetone, sodium citrate, ammonium sulfate, magnesium sulfate and tryptic soy broth (TSB) were purchased from Sigma-Aldrich. Agar was purchased from Fisher Scientific. Tryptone was purchased from EMD Millipore. Monomethyl ether hydroquinone (MEHQ) inhibitor (400–600 ppm) was removed from the PEGDA monomer by running the stock solution through a prepacked column (Sigma Aldrich). Sodium hydroxide inhibitor was removed from the NVP monomer by passing the stock solution through a 0.2 µm syringe filter. All other chemicals were used as received.
Prepacked column
Manufactured by Merck Group
Sourced in United States
Prepacked column is a type of laboratory equipment used for chromatographic separation and purification of various compounds. It consists of a cylindrical column pre-filled with a specific stationary phase material, ready for immediate use. The core function of a prepacked column is to facilitate efficient separation and isolation of target analytes from complex mixtures.

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.
