Preparation of Ionic Soluble IBP

Check if the same lab product or an alternative is used in the 5 most similar protocols
The required amount of IBP powder (200 mg) was dissolved in 10% methanol (CH3OH; Thermo Fisher Scientific) and dissolved in DI water in a 250 mL volumetric flask. It was then stirred for 12 h, sonicated for 2 h, and filtered using a 0.45 μm pore-size cellulose acetate membrane filter. A sodium chloride (NaCl) solution was added to the filtrate to create ionic strength (0.01 M) in the solution. The pH was adjusted to 7 using a sodium phosphate (Na3PO4) solution.

PCL (Mn 80 000 g/mol, Sigma Aldrich Chemistry, 440 744) scaffolds were produced using 12 wt% polymer in 1:7.3 chloroform (CHCl3, Sigma Aldrich, ReagentPlus, 132950) to methanol (CH3OH, Fisher Chemicals, HPLC grade, CAS: 67‐56‐1) volume ratio solvent. IME Technologies EC‐CLI electrospinning equipment was used with a translation nozzle stage and an 8 cm diameter rotating drum collector with a 19 cm spinning distance rotating at 10 rpm. The environmental parameters were controlled at 24°C and 40% relative humidity. A needle with inner diameter of 0.8 mm and outer diameter of 1 mm was used. The source voltage was set to 24 kV and collector voltage to −2 kV. The flowrate of the polymer solution was 26 μL/min. The mats that were produced were cut into smaller pieces of 20 by 10 mm for application. The scaffolds were sterilized using a cold ethylene oxide (EO) gas procedure and finally kept under vacuum for 5 days before use to remove EO residue.

13C, 19F and 31P NMR spectra were obtained either on a JEOL ECX 400 MHz NMR,
operated at 400 and 100 MHz, respectively, or a Bruker AVANCE III HD 500 MHz NMR,
operated at 500 and 125 MHz, respectively, and referenced to internal
tetramethylsilane (TMS) at 0.0 ppm. The spin multiplicities are indicated by the
symbols s (singlet), d (doublet), dd (doublet of doublets), t (triplet), q

chromatography (TLC) using 0.25 mm Whatman Diamond silica gel 60-F254 pre-coated
plates. Purification was performed on a Teledyne Isco CombiFlash Rf 200,and eluted

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.
