Sigma Aldrich Fine Chemicals Biosciences NHS Act SepharoseR 4 fast
NHS-activated Sepharose(R) 4 fast flow is a pre-activated agarose matrix that increases the choice of coupling chemistries available. Suitable for coupling amino-containing smaller proteins and peptides.NHS-activated Sepharose(R) 4 fast flow is composed of cross-linked 4% agarose beads NHS activated for coupling amino-containing proteins and peptides in process-scale applications. NHS (N-hydroxysuccinimide) coupling forms a chemically stable amide bond with ligands containing primary amino groups.This resin provides a spacer arm to the coupled ligand and is therefore particularly suitable for immobilising smaller protein and peptide ligands.NHS-activated Sepharose(R) 4 fast flow is available in a range of different bulk pack sizes and convenient pre-packed formats for easy scale-up and process development. As member of the BioProcess media range NHS-activated Sepharose(R) 4 fast flow meets industrial demands with security of supply and comprehensive technical and regulatory support.
AdipoGen Fluorescein dicaproate
Chemical. CAS 7364-90-1. Formula C32H32O7. MW 528.59. Fluorescein dicaproate is a non-fluorescent hydrophobic fluorescein derivative that can pass through the cell membrane whereupon intracellular esterases hydrolyze the dicaproate group producing the highly fluorescent product fluorescein. The fluorescein molecules accumulate in cells. Fluorescein dicaproate is a fluorogenic substrate for C6 esterase that generates green fluorescence upon esterase cleavage. Spectral Data lambdaEx 497nM, lambdaEm 516nm. Extinction coefficient 80000 cm-1 M-1.
AdipoGen Fluorescein dilaurate
Chemical. CAS 7308-90-9. Formula C44H56O7. Molecular Weight 696.91. Fluorescein dilaurate is a fluorogenic substrate for esterases/lipases and used in the pancreolauryl test for chronic pancreatitis. Spectral data lambdaex 490 nm lambdaem 514 nm in 0.1 M Tris pH 8.0 esterase.

Cayman Chemical BIotIn-HPDP 10mg
A sulfhydryl-reactive biotinylation reagent that forms a reversible disulfide linkage, used to label protein cysteines and other substrates that contain sulfhydryl groups; EAsily linked with target substrates at pH 6.5 to 7.5 in buffers such as PBS; disulfide linkage can be cleaved by reducing agents
STEMCELL Technologies GloCell™ Fixable Viability Dye UV 450, Size: 500 Tests
GloCell™ Fixable Viability Dye UV 450 is a fluorescent cell viability dye for staining live/dead mammalian cells in applications such as flow cytometry. The dye irreversibly binds intracellular and cell surface amine groups and can be utilized prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in a greater fluorescence compared to live cells in a cell viability assay.GloCell™ Fixable Viability Dye UV 450 is excited by the UV laser at 355 nm and it has a fluorescence emission maximum of 450 nm that can be detected using the 450/50 band pass filter used to detect DAPI, Hoechst 33258, etc.
AnaSpec D - Luciferin, potassium salt *UltraPure Grade*, 25mg
D-Luciferin, potassium salt *UltraPure Grade*, ; MW 318.41; (25 mg) Luminescent substrate for firefly luciferase.
AdipoGen 5-TAMRA N-succinimidyl ester
Chemical. CAS 150810-68-7. Formula C29H25N3O7. MW 527.52. Synthetic. Amine-reactive form of 5-carboxytetramethylrhodamine single isomer. Conjugates yield bright, pH-insensitive orange-red fluorescence Ex/Em ~546/579nm with good photostability.
AdipoGen Biotin Sulfone
Chemical. CAS 40720-05-6. Formula C10H16N2O5S. Molecular Weight 276.31. Biotin sulfone is an oxidized form of biotin and is as efficient as biotin in streptavidin binding and it binds to avidin with a binding ratio of 0.332 compared with biotin. Biotinylated synthetic oligosaccharides are an attractive tool, as streptavidin coated plates and beads are commercially available and widely use in serological assays. As biotin is chemically reactive, and not compatible with carbohydrate protecting group manipulation, the use of biotin sulfone tagged oligomannosides BSTO for antigen immobilization in candidiasis or allergy diagnosis has been used. The use of biotin sulfone also offers a convenient solution for both oligosaccharide synthesis and immobilization on microspheres and surface plasmon resonance sensors.
