Apexbio Technology LLC Lincomycin HCl 859-18-7 5g
Lincomycin HCl (859-18-7) is a small-molecule inhibitor targeting bacterial protein synthesis It is designed to inhibit translation by binding to the 50S subunit of the bacterial ribosome thereby blocking peptide elongation Lincomycin HCl exerts its biological activity primarily through inhibition of bacterial protein synthesis In in vitro studies Lincomycin HCl demonstrates bacteriostatic activity with reported IC50 values ranging from approximately 0 5 g/mL to 2 g/mL depending on bacterial strain and culture conditions Based on these pharmacological properties Lincomycin HCl holds research potential in selective antibiotic assays bacterial resistance studies and maintenance of cell culture sterility
Apexbio Technology LLC RNA Clean Beads(Synonyms: RNA purification beads, RNA magnetic beads, Magnetic RNA purification beads, RNA cleanup beads), 5ml.
RNA Clean Beads are magnetic microparticles designed for rapid high-throughput RNA purification from DNase-treated samples The beads function through reversible nucleic acid binding RNA molecules from 100 bp to 50 kb bind selectively to the bead surfaces upon addition of binding solution allowing separation in a magnetic field Contaminants including DNA digestion fragments primer dimers salts and residual proteins are eliminated in subsequent washing steps RNA is then eluted using sterile water or elution buffer yielding purified RNA suitable for downstream enzymatic digestion sequencing hybridization and PCR analysis This product can integrate seamlessly into automated nucleic acid purification workflows
