Check if the same lab product or an alternative is used in the 5 most similar protocols
Pure LaFeO3 was obtained through the calcination in the temperature range of 550 to 800 °C of the LaFe(C2O4)3·3H2O precursor, which was obtained previously. It was used as reagents: La(NO3)3·6H2O, (Fe(NO3)3·9H2O, 1,2-ethanediol, 2 M HNO3 solution from Merck (Darmstadt, Germany). NaOH and capecitabine (CCB) used was an analytical-grade reagent from Merck. The doubly distilled and deionised water were used for preparing all solutions.

Synthesis of α-Conotoxin Analogs

Check if the same lab product or an alternative is used in the 5 most similar protocols
The linear RgIA (GCCSDPRCRYRCR) and its analogs were folded in two steps to facilitate the formation of intramolecular disulfide bonds between Cys2 and Cys8 and between Cys3 and Cys12, forming the 1–3, 2–4 disulfide arrangement that is characteristic of α-conotoxins. The linear peptide was cleaved from the Wang resin using reagent K (trifluoroacetic acid (TFA) (Fisher Bioreagents), phenol (Arcos Organics), 1,2-ethanediol (Sigma Aldrich), thioanisole (Sigma Aldrich), H2O / 9.0:0.75:0.25:0.5:0.5 ratio by volume). The first oxidation step to close Cys2-Cys8 bridge was performed under potassium ferricyanide (4.0 mM) (Arcos Organics) and tris HCl (20 mM) (Mallinckrodt Pharmaceuticals, Surrey, United Kingdom), pH 7.5 for 45 minutes and purified via reversed-phase high-performance liquid chromatography (RP-HPLC) using a C18 column. The second disulfide bridge between Cys3-Cys12 was formed in the solution consisting of iodine (5.0 mM) in H2O, acetonitrile (ACN) (Fisher Chemical), and TFA (72.0:25.0:3.0 ratio by volume) and again, purified through RP-HPLC.

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.
