盐酸三-(2-羧乙基)膦 (TCEP)

蛋白质中胱氨酸的二硫化物交联可由 TCEP(三-(2-羧乙基)膦)还原为半胱氨酸残基。与 DTT(二硫苏糖醇)不同,TCEP 不含硫醇,因此通常不需要在硫醇修饰前将其去除了解更多信息

常见问题解答 (FAQ)

Can other reducing agents other than DTT or BME be used to reduce proteins prior to electrophoresis? For example, what about TCEP (Tris Carboxy Ethyl Phosphene)?

TCEP, Tris Carboxy Ethyl Phosphene is an alternative sulfhydryl reducing agent for protein samples. It is an extremely potent and effective reducing agent for particularly ‘difficult' proteins. It is compatible with the Tris-Glycine gels and NuPAGE gels. It should be added to the sample buffer for these systems. 20 mM final (maximum) concentration is sufficient for samples. You may add alkylating agents, e.g. Iodine (50 mM Iodoacetic acid), to prevent re-forming of S-S bonds but it is not necessary. Do not heat because this will hydrolyze much of your sample. Instead let the sample sit for several minutes at RT and then load.

Abstract
A general strategy for site-specific double labeling of globular proteins for kinetic FRET studies.
Authors:Ratner V,Kahana E,Eichler M,Haas E
Journal:Bioconjugate chemistry
PubMed ID:12236801
Site-directed mutagenesis provides a straightforward means of creating specific targets for chemical modifications of proteins. This capability enhanced the applications of spectroscopic methods adapted for addressing specific structural questions such as the characterization of partially folded and transient intermediate structures of globular proteins. Some applications such as the steady state ... More

The agouti-related protein gene (Agrp) plays an important role in body weight regulation. The mature human protein is a single polypeptide chain of 112 amino acid residues, consisting of an N-terminal acidic region and a unique C-terminal cysteine-rich domain. The disulfide structure of recombinant human AGRP was determined by chemical ... More

'The rate at which amide hydrogens located at the peptide backbone in protein/protein complexes undergo hydrogen/deuterium exchange is highly dependent on whether the amide groups participate in binding. Here, a new mass spectrometric method is presented in which this effect is utilized for the characterization of protein/ligand binding sites. The ... More

'LPS-binding proteins in plasma play an important role in modifying LPS toxicity. Significant properties have already been attributed to the LPS-binding protein (LBP). It accelerates LPS toxicity as well as incorporation into high-density lipoproteins, leading to neutralization of LPS in serum. A search for other LPS-binding components in serum, using ... More
