General description

1-Thioglycerol stimulates the synthesis of porphyrin in aerobically growing Escherichia coli. [1] It is an inhibitor of glycerol kinase activity in vitro and in situ.

Application

1-Thioglycerol has been used in a study to assess the manipulation of aqueous growth of CdTe nanocrystals. [2] It has also been used in a study that investigated the effect of surface attachment on ligand binding. [3]

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).

Questions

1–4 of 4 Questions  

  1. What could be causing contamination of cell culture experiments while using M1753? Also, how should M1753 be added to the cell culture media?

    1 answer

    1. To avoid contamination, sterile filtration is highly recommended prior to cell culture application. Upon verification, the lab has not formulated a protocol for cell culture use. However, the following citation on M1753 for cell culture application may be of interest as a protocol reference: Im, H. (2011). "Mouse Embryonic Stem Cell Maintenance for Differentiation." Bio-101: e145. DOI: 10.21769/BioProtoc.145.

  2. How does the storage temperature relate to shipping conditions?

    1 answer

    1. 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.

  4. What is the concentration of the 1-thioglycerol?

    1 answer

    1. 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.
