<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>

<p>10X PCR Buffer (with MgCl2 ) is recommended for all PCR applications with Taq DNA Polymerases (both recombinant and native ).</p>

TRIzol-T Reagent is a ready-to-use reagent for the isolation of total RNA from cells and tissues. The reagent, a mono-phasic solution of phenol and guanidine isothiocyanate, is an improvement to the single-step RNA isolation method and gives high yields of Total RNA. During sample homogenization or lysis, TRIzol-T Reagent maintains the integrity of the RNA, while disrupting cells and dissolving cell components. Addition of chloroform followed by centrifugation, separates the solution into an aqueous phase and an organic phase. RNA remains exclusively in the aqueous phase. After transfer of the aqueous phase, the RNA is recovered by precipitation with isopropyl alcohol. After removal of the aqueous phase, the DNA and proteins in the sample can be recovered by sequential precipitation. Precipitation with ethanol yields DNA from the interphase, and an additional precipitation with isopropyl alcohol yields proteins from the organic phase. Copurification of the DNA may be useful for normalizing RNA yields from sample to sample.This technique performs well with small quantities of tissue (50-100 mg) and cells (5 × 106), and large quantities of tissue (≥1 g) and cells (>107), of human, animal, plant, or bacterial origin.

<p>The 25mM solution of MgCl2, (0.22μm membrane-filtered), is used for optimization of magnesium ion concentration in PCR.</p>

<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>

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>This mouse monoclonal antibody is complementary to the Zika envelope protein, with batches of the IgG1k immunoglobulin subclass available. It has been purified by DEAE column chromatography and is presented as a liquid in 0.015M potassium phosphate, 0.85% NaCl, pH 7.2.&lt;/p&gt; &lt;p&gt;Transmitted by infected mosquitoes, the Zika virus, although it causes asymptotic and mild symptoms in the majority of cases, it can lead to neurological complications and Guillain-Barr&amp;eacute; syndrome in adults. Furthermore during pregnancy, infants may be born with microcephaly and congenital malformations, known as Zika syndrome. The envelope protein located on the Zika viral membrane and to which this mouse Mab is complementary, is involved in virus and host cell surface receptor binding. It has 3 domains (I, II and III) and a stem-transmembrane domain. Domain I functions to link Domain III (which is the host cell receptor binding domain) to Domain II in order to dimerise and form a fusion loop.&lt;/p&gt; &lt;p&gt;The accessible location of the Envelope protein on the viral membrane means it can be an important target for neutralising antibodies and vaccine development. This product can further be used in the rapid lateral flow detection of Zika envelope protein and other antibody and antigen interaction dependent assays such as ELISA and western blot.</p>
