We used nine n-alkanes (Kanto Chemical Co., Tokyo, Japan), including n-octane (C8H18), n-nonane (C9H20), n-decane (C10H22), n-undecane (C11H24), n-dodecane (C12H26), n-tridecane (C13H28), n-tetradecane (C14H30), n-pentadecane (C15H32), and n-hexadecane (C16H34). Each n-alkane was put in a 13.5-mL borosilicate glass bottle without PVA foam (e.g., C8H18 PVA-free; Fig. 1a) and a bottle with PVA foam (Fuji Chemical Industries Ltd., Osaka, Japan) with an average pore diameter of 300 μm (e.g., C8H18 PVA-300; Fig. 1b). We made one each of these phantoms. The molecular size of the n-alkanes represented substrate viscosity, and the placement of PVA represented the viscosity of the tissue substance and the tissue structure.

All of the reagents used in this study were of analytical grade. Deionized water was prepared by means of an Elix water purification system (Millipore Co. Ltd., Molsheim, France). Cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS), and 1-buthanol were obtained from Wako Pure Chemical Industries (Osaka, Japan). Polyethylene glycol #200 (PEG) and n-decane were purchased from Kanto Chemical (Tokyo, Japan) and Nacalai Tesque (Kyoto, Japan), respectively. Mineral oil (refractive index, 1.467) was purchased from Sigma-Aldrich (St. Louis, MO, USA).
Aqueous solutions of CTAB, SDS, and PEG were dissolved in water and placed into separate 5 mL vials. To prepare the emulsions, a 50-μL aliquot of a mixture containing 1-butanol and n-decane at a volume ratio of 1:1 was added to each aqueous solution, and then the mixtures were sonicated twice for 3 min each time.

Lecithin and Polyglycerol Fatty Acid Esters

Check if the same lab product or an alternative is used in the 5 most similar protocols
Soybean lecithin (PC content ≥ 95%) was purchased from Avanti Polar Lipids, Inc. (AL, USA) . n-Decane was purchased from Kanto Chemical Co., Inc. (Tokyo, Japan) . n-Decane was used as the oil component to compare with other lecithin reverse wormlike micellar systems. All polyglycerol fatty acid monoesters (hereinafter, referred to as PGLFAs, or PGLmFAn: where m is the degree of polymer-ization of the polyglycerol part and n is the number of carbon atoms in the saturated fatty acid part) were donated by Daicel Co., Ltd. (Tokyo, Japan) . In this study, we used decaglycerol monohexanoic acid ester (PGL10FA6) , decaglycerol monodecanoic acid ester (PGL10FA10) , decaglycerol monotetradecanoic acid (PGL10FA14) , decaglycerol monooctadecanoic acid ester (PGL10FA18) , hexaglycerol monodecanoic acid ester (PGL6FA10) , eicosaglycerol monodecanoic acid ester (PGL20FA10) and tetracontaglycerol monodecanoic acid ester (PGL40FA10) . The moisture content of all PGLFAs was below 0.1%. All chemicals were used without further purification. The molecular structures of lecithin and a polyglycerol monofatty acid ester (PGL10FA10) are shown in Scheme 1.

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.
