Description: The newly identified Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has posed a serious threat to human health. A rapid and effective Assay kit detecting the levels of anti-SARS-CoV-2 in human serum can facilitate research on characterization of antibodies produced in response to SARS-CoV-2 infection.

Description: HCoV-229E Spike Protein, His Tag (SPN-H52H3) is expressed from human 293 cells (HEK293). It contains AA Cys 16 - Pro 1115 (Accession # P15423-1 (TI 871-872 PP)).The recombinant protein is expressed from human 293 cells (HEK293) with T4 fibritin trimerization motif and a polyhistidine tag at the N-terminus. Proline substitutions TI 871-872 PP are introduced to stabilize the trimeric prefusion state of the spike protein.

Description: COVID-19 Spike Protein a.a. 1000-12000

Description: SARS Spike glycoprotein C, recombinant protein from E. coli.

Description: SARS Spike Protein (S1 Domain)

Description: COVID-19 Spike Protein a.a. 800 to 1000

Description: Goat polyclonal to Spike protein of Middle East respiratory Syndrome coronavirus. Coronaviruses access host cells by membrane fusion, a process mediated by specific fusion or “spike” proteins on the virion, often activated by cellular proteases.

Description: Since April 2012, cases of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) have been identified in the following countries: Saudi Arabia, Qatar, Jordan, the United Arab Emirates, Oman, Kuwait, Yemen, Lebanon, Iran, Algeria, the United Kingdom, France, Italy, Greece, Germany, the Netherlands, Austria, Tunisia, Egypt, Malaysia, Turkey and the United States of America. Coronaviruses are the cause of the common cold, SARS (severe acute respiratory syndrome) and other severe illnesses with high mortality rates, all are classified into coronavirus family. MERS-CoV is a new type of SARS found in the coronavirus family causing severe pneumonia with sudden and serious respiratory illness with high mortality rates as well. Since January 27th 2015, the WHO has reported 956 human cases, including 351 deaths. More cases of the new coronavirus strain are expected. Like in other coronaviruses, large surface spike glycoprotein is a central structural protein of this virus; it is located above the virion surface to bind and enter into the target cell. Spike protein has 2 domains- S1 and S2. The S1 domain is responsible for cellular tropism and interaction with target cell, while the S2 domain is responsible for membrane fusion. The C-terminal of S1 domain contains a receptor binding domain, and is also a potential target for vaccine development and an antigen for diagnosis.

Description: SARS Spike protein (aa 1-1190) [His], recombinant protein from HEK 293 cells.

Description: SARS-CoV-2 Spike S2, His Tag (S2N-C52H5) is expressed from human 293 cells (HEK293). It contains AA Ser 686 - Pro 1213 (Accession # QHD43416.1). Proline substitutions (F817P, A892P, A899P, A942P, K986P, V987P) are introduced to prevent the formation of aggregates in the course of protein production.

Description: COVID-19 Spike S1 protein a.a. 1 to 800
