Upstate s KinEASE FP and Genospectra s Express-si Delivery Reagent

Premium

Serologicals last week announced that its subsidiary Upstate has launched a red-shifted assay for its KinEASE FP fluorescence polarization products platform.

According to Upstate, the KinEASE FP product was previously limited to use with the green-shifted dye fluorescein. The new red-shifted dye, Upstate said, can produce clearer results by reducing compound interference issues that tend to occur on in the bluer end of the spectrum.

The company said that the assay is ideal for in-house use on smaller sample sizes from bench-top plate screening through robotic primary screening.


Genospectra said last week that it has introduced the Express-si delivery reagent for siRNAs.

According to the company, the reagent uses a unique technology that avoids the endocytic pathway, preventing the problem of endosomal or lysosomal degradation.
