Silica gel 60 chromatography plates

Manufactured by Merck Group
Sourced in Germany, Spain

Silica gel 60 chromatography plates are a type of thin-layer chromatography (TLC) media used for the separation and analysis of a variety of compounds. They consist of a thin layer of silica gel applied to a rigid support, typically glass or aluminum. The silica gel provides a stationary phase for the separation process, while the mobile phase, such as a solvent, carries the sample components through the media. These plates are commonly used in analytical chemistry and organic synthesis for the purification and identification of organic compounds.

Ultrafiltered fetal bovine serum (FBS) was from Natocor (Cordoba, Argentina). Restriction enzymes and other molecular biology reagents were from Promega (WI, US). [1-14C]oleic acid ([14C]-OA) and [6-3H]thymidine were from Amersham Biosciences-GE (MA, US). Fatty acid-free bovine serum albumin (BSA), mouse anti-β-actin monoclonal antibody, anti-mouse IgG peroxidase conjugate and anti-rabbit IgG peroxidase conjugate were purchased from Merck-Sigma (Darmstadt, Germany).

Aflatoxin B1 detection protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
After AFB1 extraction with chloroform, samples were filtered using 0.45 µm syringe filters (Fisherbrand, Spain) and an aliquot of 1 mL was evaporated in a vacuum concentrator, Eppendorf™ Concentrator Plus with Pump and GB Plug (Fisher Scientific, Madrid, Spain).
Silica gel 60 chromatography plates (Merck, Germany) were used, and AFB1 presence was determined according to the protocols described elsewhere [37 (link),38 (link)].
Samples and AF standards were re-suspended with 500 µL toluene/acetonitrile (95:5) (Panreac, Spain). Then, 10 µL of each sample was spotted on the plate. Toluene/acetone/acetonitrile (1:1:1 (LabKem, Barcelona, Spain)) was used as a mobile phase. Toxins were visualized under ultraviolet light (Spectronics, Westbury, NY, USA).

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.
