Overview

Safely study the spike protein from emerging SARS-CoV-2 variants 

As potentially more transmissible variants of SARS-CoV-2 emerge, understanding how mutations in the spike protein impact SARS-CoV-2 behavior is critical. With the pPACK-SPIKE™ B.1.525 Variant Spike Protein Lentivector Packaging Mix, you can safely characterize the SARS-CoV-2 S1 spike protein from the emerging lineage B.1.525 [1], which contains the following mutations:

  • ΔH69/V70
  • Q52R
  • E484K
  • D614G
  • Q677H
  • F888L

Designed to efficiently package most third-generation lentivectors, the pPACK-SPIKE B.1.525 Variant Spike Protein Lentivector Packaging Mix speeds and simplifies preparation of lentiviral particles pseudotyped with the SARS-CoV-2 ΔH69/V70, Q52R, E484K, D614G, Q677H, F888L spike glycoprotein, making it an ideal reagent for vaccine and antiviral drug discovery projects.

Based on SBI’s highly cited pPACKH1 packaging system but with a truncated SARS-CoV-2 ΔH69/V70, Q52R, E484K, D614G, Q677H, F888L Spike protein [1] replacing the standard VSV-G envelope protein, the pPACK-SPIKE B.1.525 Variant Spike Protein Packaging Mix consists of three plasmids that produce all of the structural and  replication proteins needed to transcribe and package an RNA copy of an expression lentivector into recombinant, ΔH69/V70, Q52R, E484K, D614G, Q677H, F888L “Spike” pseudotyped lentiviral particles. As a result, you can conduct a range of SARS-CoV-2 studies under BSL-2 conditions, including neutralization assays, studies of virus interactions with host surface proteins, and the development of vaccines and therapeutics.

For added convenience we also offer pPACK-BALD™, an envelope protein-free lentivector packaging mix that can be used as a negative control for any pPACK-SPIKE study, or for creating lentivirus particles pseudotyped with the envelope protein of your choice.

  • Compare with our full range of pPACK-SPIKE S protein pseudotyped lentiviruses to better understand emerging variants
  • Use with pPACK-BALD™, an envelope protein-free lentivector packaging system that is an ideal negative control

pPACK-SPIKE B.1.525 Variant Spike Protein Lentivector Packaging Mix is available as stand-alone packaging mixes with sufficient plasmids for 10 reactions (standard size) or 25 reactions (XL), as well as in a convenient kit format that includes PureFection™ Transfection Reagent and PEG-it Virus Precipitation Solution.

How It Works

pPACK-SPIKE is easy to use—simply co-transfect the pPACK-SPIKE Plasmids and your lentivector construct into 293TN producer cells or other lentiviral production cells, isolate pseudoviral particles with an optional concentration step, and conduct your studies.
