The Streptavidin Coated Beads, based on superparamagnetic or non-magnetic beads covalently coated with streptavidin, are designed to bind a variety of biotinylated molecules in immunoprecipitation, immunoassay(ELISA), cell sorting, protein interaction studies, protein/DNA hybridization reaction or even DNA sequencing application.

Sunlong Biotech^TM 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. Sunlong Biotech™ Streptavidin covalently connects the SA to the solid carrier surface by using the patented protein coupling technique of Sunlong, 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.

4. Acridine ester direct chemiluminescence

On FT4, Sunlong Biotech^TM shares the close measured value with that of the control magnetic beads, and the ratio is good。

5. ALP indirect chemiluminescence

Case 1 DAS-ELISA（HRP）MYO Test

Sunlong Biotech^TM 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（AP）tlgE Test

Conclusion：After calibration，the overall signal of Sunlong Biotech^TM is consistent with that of competing products, and linear regression R and slope are also ideal.

6.  Electrochemistry（PCT，DAS-ELISA）

Conclusion：In PCT, Sunlong Biotech^TM has higher chemiluminescence signal, better separation and more sensitive detection.
