![N-[2-(Dansylamino)ethyl]maleimide BioReagent, suitable for fluorescence, ≥99.0% (HPLC)](/deepweb/assets/sigmaaldrich/product/structures/318/294/efefa674-7883-4fc7-ad57-ea90ff85069a/640/efefa674-7883-4fc7-ad57-ea90ff85069a.png)
The B1267 Biotin-maleimide is a white powder that is soluble in DMSO at 10mg/ml, resulting in a clear colorless solution. A stock solution of the product in DMSO at 20 mg/ml can be prepared without the need for heat. This solution can then be diluted 1:10 with an aqueous buffer system, such as PBS or other. Concentrations of 40-50 mg/ml can also be prepared, but heat, i.e. 40°C, is needed. For most applications, a stock of 20 mg/ml would be suitable.

일반 설명
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[1].
애플리케이션
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[2].
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

The redox-based protein S-nitrosylation is a conserved mechanism modulating nitric oxide (NO) signaling and has been considered mainly as a non-enzymatic reaction. S-nitrosylation is regulated by the intracellular NO level that is tightly controlled by S-nitrosoglutathione reductase (GSNOR). However, the
