In a recent Nature Biotechnology paper, authors have found potential for fluorescent peptides to illuminate nerves during surgery. A frightening complication of surgery can result in paralysis, chronic pain from unintended peripheral nerve damage. To visualise and avoid these nerves has always been challenging. For example, if the nerves are invaded by a tumour, or, if surgery is required in the setting of trauma or infection, the affected nerves might not look as they normally would, or their location may be distorted. Scientists at the University of California San Diego (UCSD) have developed fluorescent peptides; referring to these as “Light-up Peptides” to visualise nerves during surgeries. |

Cyanagen are CRB’s latest supplier of bright, cost-effective and non-proprietary (free to use) fluorescent dyes. The CHROMIS product line is a selection of the newest fluorescent labels available today. Dye structures were carefully chosen to provide top-notch brightness performances, improving bioanalytical assays to the highest level. |
Eight different basic structures span the full working range of wavelength, starting from 400 nm up to 870 nm. Each fluorescent compound is available with many different reactive moieties while retaining the photophysical features of the parent dye. |
|
Furthermore, a completely new level of chemistry has been developed to provide the same fluorescent label with different charge values (anionic, cationic, zwitterionic and neutral). |
