Versatile Analyte Selection Technology (VAST)

VAST Enabled Advanced CLIA and ELISA Test System
for Multiple Parameters from A Single Kit

Every immunoassay demands sensitivity, linearity, clinical correlation and a robust test system. Recognizing the need of a flexible immunoassay reagent platform, VAST reagent format has been developed. VAST is based on an advanced technology, designed and developed to meet these demands and offer total independence in immunoassay testing.
Technology: Streptavidin-Biotin Based Assay

VAST based assays are built on Streptavidin-Biotin based advanced assay format. Streptavidin coated plates provides a generic surface for immobilization of any biotinylated molecule and preserves its activity much better than classical direct passive adsorption based assay technology. Streptavidin-Biotin offers multiple advantages and also provides the flexibility to the user to perform multiple analytes from a single kit.

Advantages of Streptavidin-Biotin VAST kit are as follows:

  • Highly thermostable
  • Offers 4-fold accelerated sensitivity
  • Highly specific for biotin hence makes the assay highly specific
  • Common streptavidin capture makes the solid phase common for all the analytes
  • Offers higher sensitivity and specificity
  • Rugged test system
  • The inert nature of streptavidin makes the assay extremely robust during usage
  • Offers flexibility and ease of selecting any parameter as per requirement of the user

VAST kit uses combination calibrators to deliver dramatic flexibility and cost efficiency to clinical laboratories. VAST kits are best suited for Indian clinical laboratories due to their higher stability and sheer flexibility. Development of VAST based immunoassays for multiple parameters has re-defined immunoassays and made quantitative estimation possible for many analytes. It offers a variety of pack sizes to suit individual needs, larger shelf life and affordable cost per test. VAST has revolutionized the immunoassay industry by offering true democracy for the user.
