Cayman Chemical BIotIn-X-NHS 500mg
A compound used to attach biotin to primary amines, such as those found on lysines on the surface of proteins; contains six-atom spacer arm
Biotium CF568 Biocytin
Fluorescent biocytin conjugates are cell-impermeant, fixable polar tracers with biotin and an aldehyde-fixable primary amine groups. Polar tracers are commonly used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during pinocytosis. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Red fluorescent CF568 dye has excitation/emission at 562/583 nm.
Medchemexpress LLC Sulfo-Cy3 Azide | 1801695-56-6 | C35H46N6O10S3 | 5 MG
Sulfo-Cy3 Azide is a water-soluble fluorogenic dye that contains an azide group, facilitating Click Chemistry. This dye is suitable for labeling sensitive molecules, such as proteins.
- Can participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) with alkyne-containing molecules.
- Can undergo ring strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.
Sino Biological Protein LASV LASV-G Biotin 20U
A DNA sequence encoding the Lassa virus strain Mouse/Sierra Leone/Josiah/1976 GP / Glycoprotein (P08669) (Thr59-Asp432) was expressed with a C-terminal polyhistidine tag followed by an AVI tag The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed
Cayman Chemical FAM AzIde 6-Isomer 5mg
A clickable form of 6-FAM; has been used to label EdU for use in cell viability, proliferation, and cell cycle progression assays in cancer cells; a related derivative, 6-FAM, displays excitation/emission maxima of 492/518 nm, respectively
Cayman Chemical BIotIn SulfoxIde 5mg
A racemic mixture of biotin (R)-sulfoxide and biotin (S)-sulfoxide
Cayman Chemical BIotIn-azIde 1mg
A form of biotin with a terminal azide group; is used to add biotin to other molecules that bear either an alkyne group, through click chemistry, or a phosphine group, using Staudinger ligation
