Phospholipon 90G (soybean phosphatidylcholine) (P90G) was kindly donated by Lipoid (Steinhausen, Switzerland). Cholesterol and B12 (purity 95%) were purchased from Acofarma (Madrid, Spain). Tween 80, phosphate salts, and sodium chloride to prepare buffers were from Scharlab (Sentmenat, Spain). Regenerated cellulose dialysis membranes with a cut-off of 14kDa (Spectra/Por® molecular porous membrane tubing) for the in vitro release studies were acquired from Repligen (Waltham, MA, USA). HPLC-quality water obtained by Milli-Q purification (Millipore, Madrid, Spain) with resistance > 18 MΩ cm and TOC < 10 ppb was used for liposome reconstitution and HPLC analysis. Methanol for the HPLC mobile phase was purchased at VWR International (Radnor, PA, USA). For the tape-stripping studies, adhesive tape Tesafilm kristall-klar (33 mm × 19 mm, cut to 30 mm × 19 mm sections) was obtained from Tesa (Hamburg, Germany); Parafilm Sealing Film—50 mm (2”) Film Width × Roll Length 75 m (Parafilm, Madrid, Spain) was used; glass beads were obtained from MERCK (Madrid, Spain). Pig ears were procured from a local slaughterhouse (Mercavalencia, Valencia, Spain).
Spectra por molecular porous membrane tubing
Manufactured by Repligen
Sourced in United States
Spectra/Por® molecular porous membrane tubing is a laboratory product designed for various applications. It is a semi-permeable membrane tubing that allows the passage of molecules based on their size and weight. The core function of this tubing is to facilitate the separation, concentration, and purification of molecules in various research and industrial processes.

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.
