General description

Dimethyl sulfoxide (DMSO) is an aprotic solvent. Therapeutic and toxic molecules that are not soluble in water are often soluble in DMSO. Liquid nitrogen used in conjunction with a cryoprotective agent such as DMSO is a widely used method for preserving cells. DMSO is used to prepare stock solutions of various molecules and is also used as a control for these molecules. It has been used in cell migration assay for dissolving post-migration cells. BPC-tested DMSO also meets the requirements of biotechnology and tissue engineering applications.

Application

Dimethyl sulfoxide has been used as a vehicle control to culture and induce hepatic stellate cells (HSCs) activation in vivo.[1][1] It has also been used to prepare a stock solution to study the cytotoxicity of ferulic acid (FA) on nucleus pulposus (NP) cells.[2]

Features and Benefits

Ready-to-use sterile filtered product conveniently packaged in septum screw-capped amber bottles. Meets USP and EP testing requirements

Caution

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.

Questions

1–10 of 15 Questions  

  1. Hi, what is the difference between DMSO product# D2438 and D2650? What is Hybri-Max vs. BioPerformance certified and meets USP testing specification?

    1 answer

    1. Both D2438 and D2650 are suitable for cell culture. The D2650 is part of the Hybri-Max™ product line. Hybri-Max products have been tested for use in hybridoma creation and culture. The D2438 is part of the BioPerformance Certified group of products. These products are tested and optimized for use in biological applications. For this product and a number of others, this includes testing to meet USP and EP guidelines. Please see the links below to review a sample Certificate of Analysis for each item.

  3. El DMSO es sensible a la luz, hay que tomar alguna precaución al respecto?

    1 answer

    1. This product is packaged in amber glass and is protected from light. The 10 mL size is packaged in a sealed ampule. Once opened, any content that is not used should also be stored in amber glass. For long term storage, the material may also be stored under inert gas to preserve the shelf life. Note that this material has a tendency to absorb water. Containers should be tightly sealed.
