Biotin-11-dCTP is a biotinylated deoxynucleoside triphosphate and an important DNA labeling reagent. In random primer DNA labeling reactions, Biotin-11-dCTP incorporates into newly synthesized DNA strands to generate labeled DNA probes suitable for hybridization applications. In addition, Biotin-11-dCTP can serve as a substrate for terminal deoxynucleotidyl transferase to end-label oligonucleotides for telomere sequence detection, or to label the cut ends of linearized DNA molecules, thereby supporting streptavidin-based electron microscopy analysis. For example, Biotin-11-dCTP can label the cut ends of linearized DNA molecules under the action of dGTP and avian myeloblastosis virus reverse transcriptase .

Synonyms: Biotin-LPS, from Escherichia coli (O111:B4)
Biotin-Lipopolysaccharide, from E.coli O111:B4 (Biotin-LPS, from Escherichia coli (O111:B4)) is a biotin-conjugated Lipopolysaccharide (LPS) (HY-D1056A1) that can be coupled with streptavidin protein. Biotin-Lipopolysaccharide, from E.coli O111:B4 can be used to identify Lipopolysaccharide ligands. Lipopolysaccharides, from E. coli O111:B4 (LPS, from Escherichia coli (O111:B4)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O111:B4) and are classified as S (smooth) type LPS. Lipopolysaccharides, from E. coli O111:B4 possess the typical three-part structure: O-antigen, R3-type core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O111:B4 activate TLR-4 in immune cells and can cause significant gastric diseases. Lipopolysaccharides, from E. coli O111:B4 can also induce M1-type polarization in mouse macrophages .
It is recommended to prepare a solution with concentration ≥2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.
