SARS-CoV-2 NSP1 Protein (His)

Cat. No.: HY-P70127
COA Handling Instructions

The ORF1ab gene is a specifically expressed gene of SARS-CoV-2 and can be quickly and sensitively detected to indirectly indicate the level of SARS-CoV-2. The ORF1ab protein is associated with viral replication and transcription, inhibition of host translation machinery, and suppression of host immune responses. SARS-CoV-2 NSP1 Protein (His) is the recombinant Virus-derived SARS-CoV-2 NSP1 protein, expressed by E. coli , with C-6*His labeled tag. The total length of SARS-CoV-2 NSP1 Protein (His) is 180 a.a., with molecular weight of ~25.0 kDa.

Background

The ORF1ab gene is a specifically expressed gene of SARS-CoV-2 and can be quickly and sensitively detected to indirectly indicate the level of SARS-CoV-2. In the evolutionary dynamics of the novel COVID-19 pandemic, SARS-CoV-2 early evolved into at least three phylogenetic groups characterized by positive selection of specific residues of the accessory proteins ORF3a and ORF8. The five known human betacoronaviruses all have four major structural proteins (E, M, N, and S) and 16 nonstructural proteins (ORF1ab) co-encoded by ORF1a and ORF1b, which are involved in the pathogenicity of the virus. and infectivity. Three of these genes (E, S, and ORF1ab genes) are characterized by strong positive selection in human betacoronaviruses, affecting codons located in functionally important protein domains. ORF1ab protein plays an important role in inhibiting host translation machinery, viral replication and transcription, and suppressing host immune responses. An electrochemiluminescence (ECL) biosensor based on dual-probe hybridization has been developed, using the detection model of "magnetic capture probe-targeted nucleic acid-Ru(bpy)32+ labeled signal probe" to detect the ORF1ab target gene. detection.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
