Gels, combs & casting accessories

Combs are specific to the gel system, so start with the system named in the product title and choose from there. Then decide on the number of teeth, which sets how many samples you load, and the thickness, for example 1 or 1.5 mm, which must match the spacers of your casting set. Standard combs suit routine runs, microwell combs small volumes and preparative combs one wide well for recovering a band. Tanks and power supplies are in electrophoresis systems and power supplies. Send your gel system and we will find the comb: sales@luminixhealth.com.

You need acrylamide and a cross-linker, such as N,N'-methylene bisacrylamide, or a ready-made solution; TEMED and an initiator to start polymerisation; a gel buffer; and glass plates, spacers and combs of matching thickness. Buffers are in biological buffers. Acrylamide is toxic as a monomer: read the GHS hazard label, wear gloves and weigh powder in a fume hood, or choose a solution to avoid dust. Pour the separating gel first, overlay it, then add the stacking gel and comb. Questions? Ask sales@luminixhealth.com.

A gel, a comb and a casting tray make the slab a sample runs through. Agarose percentage, or the acrylamide mix, sets the sieve. The comb thickness and the number of teeth set the wells. Precast and hand-cast gels are different products. A comb for a different tray does not seal.

Electrophoresis pulls charged molecules through a gel. Smaller ones move farther. Agarose gels separate nucleic acids. Polyacrylamide gels separate proteins. A comb forms the wells. A power supply holds the voltage or the current. The gel percentage is the sieve. A marker lane is how the bands are named. The methods are in the PubMed literature. Sequences of the nucleic acids are on NCBI Nucleotide.
