COVID-19 Antigen Lateral Flow Assay Development

In response to the COVID-19 pandemic, Creative Diagnostics is now offering the SARS-CoV-2 nucleoprotein antibody pair for rapid COVID-19 antigen assays to equip healthcare workers for rapid COVID-19 antigen detection. We also offer SARS-CoV-2 antigen extraction buffer tubes that can be used as packing supplies for SARS-CoV-2 antigen extraction.

SARS-CoV-2 Nucleoprotein Antibody Pair for Rapid COVID-19 Antigen Assays

The global COVID-19 pandemic has created an urgent demand for accurate rapid point of care testing. Antigen-based assays are suitably inexpensive and can be rapidly mass-produced, but sufficiently accurate performance requires highly optimized antibodies and assay conditions. Creative Diagnostics team has tested hundreds of anti-nucleocapsid antibody pairs to recommend you the best pair for further development of an LFA for SARS-CoV-2 Antigen.

SARS-CoV-2 MAb Pairs with Proven Performance in Commercially Launched Rapid Antigen COVID-19 Assays

Recommended pairs in lateral flow：

Creative Diagnostics has confirmed that the SARS-CoV-2 Nucleocapsid antibody pair (Catalog# CABT-Z727H & CABT-Z728H) is capable of detecting the conserved nucleoprotein domain of SARS-CoV-2 variants of interest including Omicron (B.1.1.529) in various commercially available COVID-19 rapid antigen tests.

SARS-CoV-2 Antigen Extraction Buffer Tubes

Extraction Buffer Tubes Brochure

These plastic tubes are designed to extract SARS-CoV-2 antigen from nasopharyngeal swab, which can be used as packing supplies for SARS-CoV-2 Rapid Antigen Test development and production.

PRODUCT HIGHLIGHTS

• Soft plastic that allows easy squeeze on the tube sides to fully extract the liquid from the swab
• Slim tube design reduces the need for the amount of extraction buffer, thereby increasing the concentration of the virus antigen in the sample and improving the positive detection rate of virus antigen
• Integral dispensing tip design
• Provide customizing and OEM services

SARS-CoV-2 Antigen Extraction Buffer

The lysis buffer is used for rapid extraction of virus antigen from virus cultures and throat swab samples. This product can improve virus lysis efficiency and the accuracy of antigen detection. It is suitable for various diagnostic technology platform, such as colloidal gold immunoassay, immunofluorescence chromatography and chemiluminescence. This product is provided in liquid form with pH 7.4, which contains Tween-20, ProClin-300 etc.

We remain focused on our mission to serve life scientists to achieve their mission, faster. We know that many scientists are still diligently pursuing their research, particularly those focused on COVID-19. We continue to support our customers and partners worldwide.
