Spike (P.1 Variant) (SARS-CoV-2) Pseudotyped Lentivirus (Luc Reporter)

78144-1 100 µl
EUR 835
Description: In Brazil, a variant called P.1 was first identified in the summer of 2020. This variant has many mutations that may lead to higher transmissibility and infectivity. The Spike (P.1) (SARS-CoV-2) Pseudotyped Lentiviruses were produced with SARS-CoV-2 Variant Spike (Genbank #QHD43416.1 with P.1 mutations (L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, D614G, H655Y, T1027I) as the envelope glycoproteins instead of the commonly used VSVG. These pseudovirions contain the firefly luciferase gene driven by a CMV promoter, therefore, the spike-mediated cell entry can be measured via luciferase activity. The Spike (P.1) (SARS-CoV-2) pseudotyped lentivirus can be used to measure the activity of neutralizing antibody against SARS-CoV-2 (P.1) variant using a Biosafety Level 2 facility._x000D_

Spike (P.1 Variant) (SARS-CoV-2) Pseudotyped Lentivirus (eGFP Reporter)

78159-1 100 µl
EUR 835
Description: The pandemic coronavirus disease 2019 (COVID-19) is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). As the first step of the viral replication, the virus attaches to the host cell surface before entering the cell. The viral Spike protein recognizes and attaches to the Angiotensin-Converting Enzyme 2 (ACE2) receptor found on the surface of type I and II pneumocytes, endothelial cells, and ciliated bronchial epithelial cells. Drugs targeting the interaction between the Spike protein and ACE2 may offer protection against the viral infection.

These pseudovirions contain the enhanced green fluorescent protein (eGFP) gene driven by a CMV promoter, therefore, the spike-mediated cell entry can be determined via eGFP fluorescence.

Spike (BQ.1, Omicron Variant) (SARS-CoV-2) Pseudotyped Lentivirus (Luciferase Reporter)

78697-1 100 µl
EUR 835
Description: The pandemic coronavirus disease 2019 (COVID-19) is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). As the first step of the viral replication, the virus attaches to the host cell surface before entering the cell. The viral Spike protein recognizes and attaches to the Angiotensin-Converting Enzyme 2 (ACE2) receptor found on the surface of type I and II pneumocytes, endothelial cells, and ciliated bronchial epithelial cells. Drugs targeting the interaction between the Spike protein of SARS-CoV-2 and ACE2 may offer protection against the viral infection. Omicron Variant was identified in South Africa in November of 2021. This variant has a large number of mutations that allow the virus to spread more easily and quickly than other variants. As of May 2022, Omicron variants were divided into seven distinct sub-lineages: BA.1, BA.1.1, BA.2, BA.3, BA.2.12.1, BA.4, and BA.5. As of October 2022, several new BA.5 sub-lineages (e.g. BQ.1, BQ.1.1, BF.7) have been designated._x000D_The spike protein of BQ.1 omicron variant has additional mutations (K444T and N460K) based on the BA.5 variant. The Spike (BQ.1, Omicron Variant) (SARS-CoV-2) Pseudotyped Lentiviruses were produced with SARS-CoV-2 Spike (Genbank Accession #QHD43416.1 containing all the Omicron BQ.1 mutations; see below for details) as the envelope glycoprotein instead of the commonly used VSV-G.

Spike Trimer (S1+S2) (P.1 Variant), His-Tag (SARS-CoV-2)

100989-1 100 µg
EUR 320
Description: Recombinant SARS-CoV-2 Spike protein in its homotrimeric form, containing S1+S2 subunits and encompassing amino acids 16-1213. This protein corresponds to SARS-CoV2 Variant P.1 originally discovered in Brazil and contains 11 mutations in addition to 682RRAR685>A, K986P and V987P, as listed below. The construct also contains a C-terminal His-tag. Note that the expected MW of the S1+S2 monomer is 136kDa but migrates at a higher MW in SDS-PAGE due to glycosylation. The recombinant protein is ≥90% pure following high affinity Ni-NTA purification.
