Tlc plates silica gel 60

Manufactured by Merck Group
Sourced in Germany

TLC plates silica gel 60 are thin-layer chromatography (TLC) plates made of silica gel. Silica gel is a porous, amorphous form of silicon dioxide that is commonly used as a stationary phase in TLC. The plates provide a substrate for the separation and analysis of chemical compounds.

Azithromycin and N-[7-(4-nitrobenzo-2-oxa-1,3-diazole)]-6-aminocaproyl-d-erythro-sphingosine (C6-NBD-ceramide) were purchased from Cayman Chemical (Ann Arbor, MI, USA). In order to generate stock solutions, these compounds were dissolved in DMSO (the ultra-pure grade Hybri-Max™, Sigma-Aldrich, St. Louis, MO, USA) and were stored at −20 °C until use. l-[14C(U)]serine was obtained from Moravek (Brea, CA, USA). D7-cholesterol was purchased from Avanti Polar Lipids (Alabaster, AL, USA). FITC-conjugated mouse anti-chlamydial LPS antibody was purchased from Denka Seiken (Tokyo, Japan). DMEM with high glucose and cycloheximide was obtained from FUJIFILM Wako (Osaka, Japan). The TLC plates (Silica gel 60) were purchased from Merck (Darmstadt, Germany).

Column chromatography was performed by using Merck silica gel 60 (63–200 µm) with eluents indicated in the experimental section. Standard TLC for synthesis employed Merck TLC plates silica gel 60 on an aluminium base with the indicated solvent system. The spots on TLC were visualised either by UV–Vis (254 nm) or by staining with KMnO4.

Synthesis of Functionalized ssPalms

Check if the same lab product or an alternative is used in the 5 most similar protocols
All reagents were obtained from commercial sources and were used without further purification. Thin layer chromatography was performed on Merck TLC plates silica gel 60. 1H-NMR spectra were recorded on a JEOL ECA600 (1H 600 MHz) spectrometer. Scheme for the synthesis of the ssPalmO and ssPalmO-Paz4-C2 is shown in Scheme 1. Intermediate Compounds 1 and 2 were synthesized as described in a previous report [5] (link). Compound 1 (1.2 g, 3.9 mmol) was dissolved in acetonitrile (31 mL) at 20–25 °C, and potassium carbonate (1.3 g, 9.7 mmol) was then added. After stirring the mixture at 20–25 °C for 5 minutes, 1-piperazineethanol (5.0 g, 39 mmol) was added and the resulting solution was stirred at 25–35 °C for 13 hours. The potassium carbonate was removed by filtration, and the filtrate was evaporated to give a brown liquid, which was then dissolved in chloroform (25 mL), and the chloroform phase washed with distillated water (3 × 25 mL). The organic layer was dried over magnesium sulfate (0.60 g), the solution was filtered and evaporated to yield compound 3 (1.0 g).

Syntheses of ssPalms. Scheme for the synthesis of the ssPalmO and ssPalmO-Paz4-C2 is shown. ssPalms were synthesized according to the Synthesis of the ssPalmO, ssPalmO-Paz4-C2, and ssPalmL section.

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.
