Cayman Chemical AcrIdInIum NHS ester 10mg
The acridinium NHS ester can be used to label proteins and nucleic acids. The covalently bound acridinium NHS ester will produce chemiluminescence in the presence of hydrogen peroxide. Acridinium-labeled proteins can be used as a detection method in immunoassays.{2437,2438}
Biotium OX40 / CD134/ TNFRSF4 (Immuno-Oncology Target)(OX40/3108), Biotin conjugate, 0.1mg/mL
ThisMAb recognizes a protein of 43 kDa, identified as OX40, which is also known as CD134. OX40 is a type I integral membrane glycoprotein and member of the tumor necrosis factor/nerve growth factor receptor (TNFR/NGFR) family. It is expressed on activated T lymphocytes, hematopoietic precursor cells and fibroblasts. It functions as a T cell co-stimulatory receptor when bound by OX40 Ligand/TNFSF4 that is expressed by antigen presenting cells. OX40 thereby plays roles in T-cell activation as well as the regulation of differentiation, proliferation or apoptosis of normal and malignant lymphoid cells. OX40 is upregulated at the sites of inflammation, especially in case of multiple sclerosis and psoriatic lesions. Primary antibodies are available purified, or with a selection of fluorescent CF Dyes and other labels. CF Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF405S and CF405M are not recommended for detecting low a

Biotium 5(6)-Tetramethylrhodamine Maleimide
5(6)-Carboxytetramethylrhodamine maleimide has C6-linker that enhances the fluorescence after the dye is conjugated to proteins. The product is a direct replacement for 5(6)-carboxytetramethylrhodamine C5-maleimide (91040).Properties: Ex/Em (MeOH) = 540/565 nm; Red solid soluble in DMF or DMSO; Store at -20°C and protect from light, especially in solution; C35H36N4O6; MW: 608.66.
Biotium Tyramide Amplification Kit with HRP Streptavidin and CF488A Tyramide
Tyramide amplification, sometimes called Catalyzed Reporter Deposition (CARD), is an enzyme-mediated detection method that uses the catalytic activity of horseradish peroxidase (HRP) to generate high density labeling of a target protein or nucleic acid sequence in situ. The tyramide amplification method has been reported to increase the sensitivity by up to 100-fold compared to the conventional avidin-biotinylated complex procedure. The kit contains HRP Streptavidin CF488A dye tyramide. The dye has an excitation/emission of 490/515 nm. The kit contains sufficient reagent for 50-150 slides.
Medchemexpress LLC Desthiobiotin-NHS ester | 80750-24-9 | MFCD08062086 | 98.0% | 311.33 g/mol | C14H21N3O5 | 25 MG
Desthiobiotin-NHS ester is an amine-reactive bioconjugation reagent that couples desthiobiotin to primary amines via an N-hydroxysuccinimide (NHS) ester to form stable amide bonds. It is used for protein labeling, affinity purification, and biochemical assays where reversible streptavidin binding is desired.
- Reacts with primary amines to form stable amide bonds.
- Desthiobiotin tag enables reversible streptavidin binding for gentle elution.
- High purity (98.0%) supports consistent labeling performance.
- Available in small-scale quantities for research use, including 25 mg.
- Solid, white to off-white appearance for easy handling and storage.
- Powder stable at -20°C for extended shelf life; solutions should be stored cold.
