Biotin and derivatives
Apexbio Technology LLC Biotin-16-dCTP 200ul (5 mM)
Biotin-16-dCTP is a biotinylated derivative of deoxycytidine triphosphate (dCTP) designed for enzymatic incorporation into nucleic acids during polymerase-mediated processes Structurally it consists of a dCTP core conjugated via a 16-atom spacer arm to a biotin moiety facilitating effective interaction with streptavidin This specific biotin-streptavidin binding affinity enables applications in nucleic acid labeling detection and affinity purification protocols PCR experiments indicate that biotin-16-dCTP incorporation by Taq polymerase can reach approximately 90% substitution without considerable reduction in amplification yield demonstrating greater polymerase compatibility compared to biotin-16-dUTP analogues
Apexbio Technology LLC Sulfo-NHS-Biotin Kit (30-90 kDa) 3samples
Sulfo-NHS-Biotin Kit (30-90 kDa) is a biotinylation reagent set designed to introduce biotin molecules onto primary amines in proteins such as immunoglobulin G (IgG) The biotin molecules in this kit are activated ester derivatives (Sulfo-NHS-biotin) functioning through covalent conjugation reactions where the NHS ester group selectively reacts with primary amino groups (e g lysine residues and protein N-termini) on proteins After conjugation labeled proteins can be applied in biotin-streptavidin platforms for detection immunoassays protein immobilization and affinity purification This kit is optimized for proteins within the molecular weight range of 30-90 kDa accommodating 50-200 g protein per reaction and allows removal of excess biotin or interfering low-molecular-weight components using filtration-based purification for improved labeling quality and purity
Medchemexpress LLC CA125 Human Biotin 20ug | 20ug
The CA125 protein acts by binding to MSLN and plays a crucial role in forming a protective and lubricating barrier on mucosal surfaces This interaction promotes heterotypic cell adhesion and is suggested to play an important role in peritoneal metastasis of ovarian cancer CA125 Protein Human (Biotinylated HEK293 His-Avi) is the recombinant human-derived CA125 protein expressed by HEK293 with C-Avi C-His labeled tag
Medchemexpress LLC CXADR Mouse Biotin 100ug
CXADR protein is a key component of the epithelial apical junction complex which maintains the integrity of tight junctions and enables leukocyte migration through adhesive interactions with JAML This interaction activates - T cells and promotes tissue repair through cell signaling involving PI3 kinase and MAP kinase CXADR Protein Mouse (Biotinylated HEK293 Avi-His) is the recombinant mouse-derived CXADR protein expressed by HEK293 with C-Avi C-6 His labeled tag
