Apexbio Technology LLC NHS-SS-11-BIOTIN 50MG
NHS-SS-11-Biotin (CAS 142439-92-7) is an amine-reactive biotinylation reagent commonly used in biochemical research Structurally it possesses an N-hydroxysuccinimide (NHS) ester group that covalently reacts with primary amines of target proteins or biomolecules forming stable amide bonds and releasing sulfo-NHS This reagent features a cleavable disulfide linker and an extended spacer arm of approximately 24 3 enhancing probe accessibility to avidin or streptavidin conjugates It is utilized extensively for reversible biotinylation affinity purification or labeling studies in proteomics and cell biology applications
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
Apexbio Technology LLC Sulfo-NHS-Biotin Kit (90-180 kDa) 3samples
Sulfo-NHS-Biotin labeling is widely utilized in biochemical research to covalently conjugate biotin molecules to free amino groups on protein molecules primarily lysine residues and N-terminal amines The reaction proceeds via activated ester intermediates forming stable amide bonds that facilitate subsequent detection or purification using streptavidin-biotin affinity interactions This labeling method is routinely applied to diverse protein samples particularly immunoglobulin G and other antibodies (molecular weight 90-180 kDa) enabling downstream applications such as immunoassays Western blotting immunoprecipitation and flow cytometry analyses Commonly the labeled proteins are purified rapidly by spin-based filtration to eliminate unreacted small molecules improving purity and yield
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 BIOTIN-11-DUTP 200UL 5 MM
Biotin-11-dUTP (CAS 1221498-88-9) is a biotin-conjugated analogue of deoxythymidine triphosphate (dTTP) that can be incorporated enzymatically into DNA or cDNA sequences during polymerase reactions After integration labeled nucleic acid fragments can be detected using streptavidin coupled to horseradish peroxidase (HRP) alkaline phosphatase (AP) fluorescent molecules or bead-based capture systems This approach is frequently utilized in polymerase chain reaction (PCR) nick translation reverse transcription assays and apoptosis studies facilitating DNA probe labeling and molecular analysis workflows
