Poly (neutral) Lite Avidin

Garantee of highest signal intensity

As Supplier, e-Proteins guarantees the best prices for the highest quality.

Our customers working with the cross linking streptavidin technology have requested to e-Proteins to develop a new product with the Neutralite avidin’s advantages combined with the cross-linking streptavidin high sensitivity. 

After more than five years of research, e-Proteins has implemented a innovative process that enables to produce a Poly-neutralite avidin with a profile presenting a higher level of dimers, trimers and quadrimer comparing the the cross-linking steptavidin profile.  This innovative product is ready to use ! 

In vitro diagnostics (IVDs) is at constant search for more specificity which – in practical terms – melts down to tracking for higher signal / background ratio. Neutralite Avidin – carrying a nearly neutral charge, no oligomannosidic glycan and no Arg-Tyr-Asp (RYD) amino acids sequence – has served that specific purpose for quite some years through reducing background or non-specific bio-recognition by some 75%.

With Poly (or Oligomerized) (Neutra) Lite Avidin, e-Proteins goes one step further in increasing the intensity of the signal by some 133%, leading to an overall improvement of min 500% in specificity in comparison to the original avidin. A unique approach to high performance IVD, direct substitution, no brainer!
