General description

Biotin-maleimide is a biotin specific thiol containing reagent used to biotinylate different proteins through artificially induced or natural sulphadryl group. It can be used as a universal, multipurpose, thiol-specific probe. Biotin-maleimide can also be used in dot blots to detect protein SH groups.

Application

Biotin-maleimide- 0.01 mg/ml in PBS containing 0.1% Tween 20, incubated for 1 h at room temperature can be used to detect deprotected cysteine thiols present on immobilized peptides.
Sulfhydryl-specific biotinylation reagent. Couples by highly efficient thioether linkage. Typically used to couple to intrinsic sulfhydryls, e.g. protein, and avoid modification of primary amine.

The orientation of an immobilized antigen is important for recognition by, e.g., an antibody. When noncovalent passive adsorption is used for immobilization, the number of ways that the antigen can attach to the surface is numerous and control of how...

A biotin-containing, thiol-specific reagent, 3-(N-maleimido-propionyl) biocytin (MPB), was synthesized and used to biotinylate various proteins via native or artificially induced sulfhydryl groups. In combination with appropriate avidin- or streptavidin-conjugated markers (i.e., fluorescent, enzyme-conjugated, electron-dense, etc.), MPB essentially constitutes a universal...

Host interferon-induced transmembrane proteins (IFITMs) are broad-spectrum antiviral restriction factors. Of these, IFITM3 potently inhibits viruses that enter cells through acidic endosomes, many of which are zoonotic and emerging viruses with bats (order Chiroptera) as their natural hosts. We previously...

Significant evidences indicate that reactive oxygen species (ROS) can induce macroautophagy/autophagy under both physiological and pathological conditions. Although the relationship between ROS and autophagy regulation has been well studied, the basic mechanism by which ROS affects autophagy and the biological...
