Biological Activity

Description

Romlusevimab (BRII-198) is a neutralizing recombinant human IgG1 monoclonal antibody against the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)^[1]^[2].

Isotype

Human IgG1 lambda2

Recommend Isotype Controls

Human IgG1 lambda2, Isotype Control

Species Reactivity

Virus

IC₅₀ & Target

Severe acute respiratory syndrome coronavirus 2

In Vitro

Romlusevimab and Amubarvimab (HY-P99435) bind to distinct epitopes of the SARS-CoV-2 spike protein^[1].
Romlusevimab has an additive effect when combined with Amubarvimab^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Romlusevimab (10 mg/kg, ip, single) in combination with Amubarvimab (HY-P99435) protects animals from Omicron infection in a mouse model of SARS-CoV-2 infection^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
