Description

Safely explore increased transmissibility and other features of the spike protein from the CDC variant of concern SARS-CoV-2 Delta (B.1.617.2)
  • Based on SBI’s popular and highly cited pPACKH1 Packaging System
  • Uses codon-optimized SARS-CoV-2 “S” protein from variant Delta (B.1.617.2, originally found in India) in place of VSV-G envelope protein
  • Spike protein mutations are T19R, G142D, ?E156-157, R158G, L452R, T478K, D614G, P681R, D950N
  • Ideal for vaccine and antiviral efficacy studies under BSL2 conditions
  • Package any 3rd-generation lentivector reporter of your choice, including SBI’s popular LentiLabeler reporters

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
  • ?E156-157
  • 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, ?E156-157, 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, ?E156-157, 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, ?E156-157, 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.
