Description
COVID-19 Spike protein (S), Delta variant (L452R, T478K) Virus Like Particle was packaged in HEK293T cells using our proprietary technology. It is the replication-incompetent particles in which the native, COVID-19 S protein, Delta variant (with 6His-tag at its C-terminal) was pseudo-typed as the lentiviral particles’ surface envelope protein. [Note: This VLP has the Spike protein already expressed / presented at surface of lentiviral particle to mimic coronavirus. It is not used as lentivirus for over-expression of the Spike protein. For over-expressing COVID-19 S protein, please use lentivirus product, CAT#: LVP1439.]
To maintain the particle structure, the VLP was packaged with a non-sense sequence (Null) as the particle’s virion genomic material. this VLP will also bind onto to the cells that express the COVID-19 S protein receptor (such as ACE2).
Applications:
The S protein mutant was assembled as surface antigens for use in the development of COVID-19 diagnostics and in vaccine development and other validation assays for COVID-19 coronavirus. This VLP can be detected by anti-C-terminal 6His-tag antibody because the S protein was tagged by C-term 6His-tag.
The VLP’s titer was measured via ELISA P24 assay. Every single particle has assembled many S protein molecular on its surface. See more details in Product Manual.
Amount: 200ul/vial at 1×108 VP/ml.
CAT#: VLP018
