Overview

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

Potentially more transmissible than previous SARS-CoV-2 variants, the Delta variant (B.1.617.2) is classified as a variant of concern by the Centers for Disease Control (CDC) in the United States. This variant was initially observed in India and has since spread globally. With the pPACK-SPIKE™ Delta (B.1.617.2) Variant Spike Protein Lentivector Packaging Mix, you can safely characterize the SARS-CoV-2 S1 spike protein from lineage Delta (B.1.617.2), which contains the following mutations:

  • T19R
  • G142D
  • ΔE156-157
  • R158G
  • L452R
  • T478K
  • D614G
  • P681R
  • D950N

Designed to efficiently package most third-generation lentivectors, the pPACK-SPIKE Delta (B.1.617.2) Variant Spike Protein Lentivector Packaging Mix speeds and simplifies preparation of lentiviral particles pseudotyped with the SARS-CoV-2 T19R, G142D, ΔE156-157, R158G, L452R, T478K, D614G, P681R, D950N 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 T19R, G142D, ΔE156-157, R158G, L452R, T478K, D614G, P681R, D950N Spike protein [1] replacing the standard VSV-G envelope protein, the pPACK-SPIKE Delta (B.1.617.2) 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, T19R, G142D, ΔE156-157, R158G, L452R, T478K, D614G, P681R, D950N “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.

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.
