Descripción general

11-mercaptoundecanoic acid (MUA) has long alkane chains and carboxyl containing thiols that are highly packed and form a self-assembled monolayer (SAM). It modifies the surface of nanoparticles to facilitate their dispersion into water and solvent based mediums.[1][2]

Aplicación

MUA is used for the carboxylic acid functionalization of 1-dodecanethiol-protected gold nanoparticles (AuNPs) by Murray place-displacement reaction generally utilized in biomedical applications.[3] It can also be used to modify the surface of platinum nanoparticles (PtNPs) by creating a ligand nano-assembly with a high surface coverage for use in surface-enhanced Raman spectroscopy (SERS).[4] A single cell biochip platform can be developed utilizing a cell attachment technique with MUA forming a SAM that was attached to single cells.[5] MUA may be used to prepare a tetrafluorophenyl-activated ester self-assembled monolayer to immobilize amine-modified oligonucleotides[6] and DNA.[7] It is also used to create 3D-assembled gold nanostructures for plasmonic biosensors.[8]

A tetrafluorophenyl (TFP) ester-terminated self-assembled monolayer (SAM) for the fabrication of DNA arrays on gold surfaces is described. Activated ester SAMs are desirable for biomolecule array fabrication because they readily react with amine-containing molecules to form a stable amide linkage.

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
