The SARS-CoV-2 Spike RBD Antibody (CAB20135) is a high-quality antibody developed for reliable detection and analysis of target proteins. This polyclonal antibody, raised in rabbits, is validated for use in various applications such as ELISA, Western blot, and immunohistochemistry.The SARS-CoV-2 Spike RBD is a key component of the virus responsible for binding to host cells and facilitating viral entry. Understanding the interaction between the Spike RBD and host cell receptors is crucial for developing targeted therapies, vaccines, and diagnostic tools for COVID-19.
This antibody is validated for use in WB, IF/ICC, IP, ELISA applications and has demonstrated reactivity against SARS-CoV-2 samples.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an enveloped, positive-sense, single-stranded RNA virus that causes coronavirus disease 2019 (COVID-19). Virus particles include the RNA genetic material and structural proteins needed for invasion of host cells. Once inside the cell the infecting RNA is used to encode structural proteins that make up virus particles, nonstructural proteins that direct virus assembly, transcription, replication and host control and accessory proteins whose function has not been determined.~ The structural proteins of SARS-CoV-2 include the envelope protein (E), spike or surface glycoprotein (S), membrane protein (M) and the nucleocapsid protein (N). The spike glycoprotein is found on the outside of the virus particle and gives coronavirus viruses their crown-like appearance. This glycoprotein mediates attachment of the virus particle and entry into the host cell. S protein is an important target for vaccine development, antibody therapies and diagnostic antigen-based tests.
