BeaverBeadsTM Streptavidin 280

 

1. Introduction

(SA-Biotin) system has extremely high binding affinity (Kd=10^-15), It has a wide range of applications in the biological field. BeaverBeadsTM Streptavidin covalently connects the SA to the solid carrier surface by using the patented protein coupling technique of Beaver, which can efficiently bind the ligands such as biotinylated antibodies, nucleic acids, proteins etc. The product adopts superparamagnetic microspheres with uniform size and regular morphology, which facilitates the rapid and convenient capture of target molecules and the realization of magnetic separation. This product can be equipped with automation equipment for high flux operation.

BeaverBeadsTM chemiluminescence performance is comparable to that of competitors magnetic products, which can be replaced, especially for low value samples, with better separation and more sensitive detection.


Case 2 DAS-ELISA(APtlgE Test

 

ConclusionAfter calibrationthe overall signal of BeaverBeadsTM is consistent with that of competing products, and linear regression R and slope are also ideal.
