>Antigens & Antibodies for Diagnostic Kit Development
The current methods of detecting SARS-CoV-2 infection include nucleic acid detections, antibody detections, and antigen detections. Compared to nucleic acid detections, antibody detections and antigen detections are faster and more convenient. Therefore, they are suitable for scenarios such as rapid screening and instant detection.
The sensitivity and specificity of the serological diagnostic kits are significantly affected by the quality of antigen and antibody reagents. To better support the development of the diagnostic kits, ACROBiosystems has developed a serial of high-quality antigen and antibody reagents. Furthermore, several in vitro diagnostics companies are using ACRO's reagents to develop COVID-19 serological diagnostics products. Among them, Babson Diagnostics, a US diagnostics company, successfully obtained the Emergency Use Authority from FDA and launched their chemiluminescent COVID-19 antibody detection kit employing ACRO's biotin-labeled S1 protein.
ACROBiosystems has launched matched antibody pairs specifically designed for diagnostic kits. The sensitivity of the ELISA assays using our matched antibody pairs can reach 12 pg/mL, which is very impressive. What's more, the affinity of these antibodies towards their antigens can be as low as 0.01 nM level. Thus, they are perfect for different antigen detection assays, such as chemiluminescent immunoassay, ELISA, gold immunochromatography assay, etc.
We now offer free samples to the researchers working on the diagnostic kit development. Get it now!

These antibodies were recommended for antigen detection by double antibody sandwich.
Fig 1 Immobilized Anti- SARS-CoV-2 Nucleocapsid antibody, mouse Mab (Cat. No. NUN-S46) at 4 μg/mL, add increasing concentrations of SARS-CoV-2 Nucleocapsid protein and then add Biotinylated Anti- SARS-CoV-2 Nucleocapsid antibody, mouse Mab (Cat. No. NUN-S47). Detection was performed using HRP-conjugated streptavidin with sensitivity of 12 pg/mL.
