Since the new omicron variant becomes more and more relevant, also research starts to push the new B.1.1.529 variant into the foreground. To enable the research, our supplier eENZYME worked at full blast to deliver new spike RBD proteins and new pseudoviral particles to the latest omicron variant.

Expected to be available from 21.12.2021:

SCV2-PsV-Omicron

Name

SARS-CoV-2 Pseudoviral Particles, Omicron Variant (B.1.1.529)

Description

The SARS-CoV-2 Pseudoviral Particles are replication-deficient Maloneymurine leukemia virus (MLV or MuLV) pseudotyped with the SARS-CoV-2 spike protein carrying the Omircon variant genotype.
MLV-based virus system is a better choice than HIV-based lentivirus system for making pseudoviral particles in regards of lab safety and product quality. Gag-Pol is the only component from MLV.

Applications

Our Pseudovirus Particles generate robust chemiluminescent signals in cell assays when coupled with our firefly luciferase assay kit (Catalog # CA-L165), useful for 1) screening potential inhibitors to block SARS-CoV-2 entry and viral protein; 2) measuring the activity of and screening for neutralizing antibody against SARS-CoV-2. 

Size

10 ml (2 tubes, 5 mL/tube), for 2 multi-well plates. 

Storage

 -70oC. Shipped on dry ice.

Note

1. Amenable to HTS format (96-well, 384-well and 1536-well format). 
2. HEK293-hACE2 stable cells are available seperately (Cat..#  CL-hACE2-001, CL-hACE2-002)
