General description
1-Thioglycerol stimulates the synthesis of porphyrin in aerobically growing Escherichia coli. It is an inhibitor of glycerol kinase activity in vitro and in situ. [1]
Application
Preparation Note
This product is miscible in ethanol (1 ml/ml, 50%, v/v), yielding a clear, colorless solution. It is also miscible in water (0.1 M).

The infantile form of glycerol kinase (GK) deficiency (McKusick No. 30703) (1) is characterized by adrenal cortical insufficiency, adrenal hypoplasia and developmental delay. The underlying biochemical mechanism(s) responsible for the observed clinical presentations are undetermined. Pursuant to our examination of

Mu dX(lac) insertion mutants of Escherichia coli CSH50 in which the expression of the lacZ gene was sensitive to the presence of exogenous 1-thioglycerol or dithiothreitol were isolated. Both stimulatory and inhibitory mutants were found. The existence of several thiol-sensitive

The effect of 1-thioglycerol on the expression of genes of Escherichia coli was investigated. Pulse-labeled proteins from aerobically growing, 1-thioglycerol-treated E. coli were separated by two-dimensional gel electrophoresis, and their radioactivities were compared with those of identical proteins from nontreated

Biomaterial-mediated complement activation repeatedly has been invoked as a trigger of phagocyte reactions and inflammation. However, a direct correlation between complement activation and inflammatory responses to biomaterial surfaces has yet to be established. Using an animal implantation model and gold

Nanoparticles of CdS were prepared at 303 K by aqueous precipitation method using CdSO4 and (NH4)2S in presence of the stabilizing agent thioglycerol. Adjustment of the thioglycerol (T) to ammonium sulphide (A) ratio (T:A) from 1:25 to 1:3.3 was done

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.

What is the concentration of the 1-thioglycerol?
1 answer-
The liquid is not a solution of 1-thioglycerol in some solvent. Rather, it is a neat liquid (i.e., essentially pure 1-thioglycerol). Based on a density of 1.245 g/mL and a molecular weight of 108.2 g/mole, one can calculate an effective molarity of 11.5 M. This information may be found on the M1753 product information sheet.
