Dithio-1,4-érythritol ≥99%, poudre cristalline blanche

Fournisseur: MP Biomedicals
Description: Dithioerythritol is an erythro isomer of 2,3-dihydroxy-1,4-dithiolbutane, and an isomer of 1,4-dithiothreitol which is a reagent for maintaining thiols in the reduced state; prevents oxidation of sulfhydryl-containing proteins during SDS-polyacrylamide gel electrophoresis. It also quantitatively reduces disulfides.

Guanidinium chlorure ≥99%, poudre cristalline blanche, Ultrapure

Fournisseur: MP Biomedicals
Description: Guanidine Hydrochloride is a protein denaturant and thus having an important role in molecular weight determinations.
Guanidine Hydrochloride is a strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. This strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Guanidine HCl is used in the isolation of RNA to dissociate the nucleoprotein into its nucleic acid and protein moieties. It is an inhibitor of RNase. Highly concentrated (6 - 8 M) Guanidine HCl solutions are used to denature native globular proteins. It apparently disrupts hydrogen bonds which hold the protein in its unique structure. However, there also is evidence suggesting that guanidine hydrocholoride may disrupt hydrophobic interactions by promoting the solubility of hydrophobic residues in aqueous solutions.

Guanidinium chlorure ≥99%, poudre cristalline, Ultrapure

Fournisseur: MP Biomedicals
Description: Applications
Guanidine hydrochloride can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Also used in the isolation of RNA. It is a strong chaotropic agent useful for the denaturation and subsequent refolding of protein, it can solubilize insoluble or denatured proteins such as inclusion bodies and be used for the recovery of periplasmic proteins. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Also used in the isolation of RNA.
Product Description
The crystal structure of Guanidine hydrochloride consists of a network of guanidinium cations and chloride anions linked by N–H•••Cl hydrogen bonds,it is a strong chaotropic agent.Guanidine HCl may agglomerate upon storage. It may appear as a free-flowing crystalline powder, a freeflowing powder with solid material dispersed throughout, or a solid. The quality of the product does not appear to be affected and solutions prepared from the free-flowing and lumpy guanidine HCl appear identical

TCEP-HCl (Tris(2-carboxyéthyl)phosphine hydrochlorure), Pierce™

Fournisseur: Thermo Fisher Scientific
Description: Thermo Scientific Pierce TCEP-HCl is a potent, versatile, odorless, thiol-free reducing agent with broad application to protein and other research involving reduction of disulfide bonds. The unique compound is easily soluble and very stable in many aqueous solutions. TCEP reduces disulfide bonds as effectively as dithiothreitol (DTT), but unlike DTT and other thiol-containing reducing agents, TCEP does not have to be removed before certain sulfhydryl-reactive crosslinking reactions.

α-Toluenesulfonyle fluorure ≥99% (par GC-FID)

Fournisseur: ENZO LIFE SCIENCES
Description: Irreversible inhibitor of serine proteases. Widely used fatty acid amid hydrolase (FAAH) inhibitor for pretreatment of brain membrane preparations when testing CB1 receptor activity. Spleen membranes used for CB2 studies do not require this pretreatment, as FAAH activity is absent in these cells. Inhibits also cysteine proteases like papain (reversible by DTT treatment, as well as internucleosomal DNA fragmentation in immature thymocytes. For a related, more stable inhibitor see AEBSF.
