SDS-PAGE is a method employed for separating proteins via electrophoresis, based on the principle that charged molecules migrate through a matrix in response to an applied electric field. The matrix utilized for this separation is polyacrylamide, which is derived from acrylamide, a compound that can be hazardous. Polyacrylamide is commonly used for the size-based separation of proteins and nucleic acids. The gel matrix forms through the free radical polymerization of acrylamide along with a crosslinking agent known as N, N-Methylenebisacrylamide. In this process, acrylamide monomers polymerize into long chains, initiated by a free radical-generating system, and these chains are linked by the cross-linker, resulting in a gel structure. This gel is crucial for effective electrophoretic separation, facilitating the analysis of biomolecules based on size.

<p>Iberiotoxin a synthetic scorpion toxin sourced from the Buthus tamulus scorpion, has disufide bonds formed between Cys7-Cys28, Cys13-Cys33, and Cys17-Cys35. This prodict can be used as a Ca2+-Activated K+ Channel Blocker (Maxi-K+ Channel Blocker). This peptide can be used in pharmacological studies to investigate the effects of Iveriotoxin on various ion channels and receptors. This product is available as a 0.1mg vial.</p>

<p>Lugdunin is a synthetic antibiotic that has been shown to inhibit the growth of bacteria by binding to the cell membrane. This binding causes a change in membrane potential, leading to inhibition of bacterial growth and death. Lugdunin is effective against Staphylococcus aureus, including methicillin-resistant strains, and has been found to be safe for use in humans. It is also active against other Gram-positive bacteria such as Streptococcus pneumoniae and Enterococcus faecalis. The enantiomer of lugdunin does not have antibacterial activity.</p>
