General description

Finding the right chemical that matches your pharma and biopharma manufacturing needs as well as regulatory demands can be a complicated challenge. With our application know-how and regulatory expertise, we support you in every step of development, scale-up, and production.As part of our Emprove® Program, our raw materials are offered with extensive documentation facilitating compliance of your pharma and biopharma product, full supply chain transparency and risk mitigation. Our SAFC® portfolio of high-quality products for pharma and biopharma manufacturing withstands strict quality control procedures and is produced according to applicable cGMP guidelines.

Application

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.

Other Notes

Due to its low microbial and endotoxin limits, Guanidinium chloride Emprove® Expert is suitable for biopharma manufacturing needs.
