N° du produit ABIN6963740

Détail du produit

Antigène: SARS-CoV-2 Spike

Type de proteíne: Recombinant

Attributs du protein: B.1.351 - beta

Origine: SARS Coronavirus-2 (SARS-CoV-2), SARS CoV-2 Beta

Source: HEK-293 Cells

Purification/Conjugué: Cette SARS-CoV-2 Spike protéine est marqué à la rho-1D4 tag.

Application: ELISA, Ligand Binding Assay (LBA)

Fonction: This is the spike protein of the mutant strain B.1.351, also commonly known as the "South Africa mutant".

Specificité: Mutation that differ from canonical sequence of SPIKE protein: del 144, K417N, E484K, N501Y, A570D, D614G, P681H, T716I, S982A, D1118H

Attributs du produit: "SARS CoV-2 full-length Spike B.1.351 Mutation"
All viruses undergo fast mutations and adept quickly to the countermeasures that the immune systems creates against them. SARS-CoV-2 of the COVID-19 pandemic is no exception here. During the pandemic multiple mutant strains arose. To help the science combat these mutants we offer the SPIKE protein of these mutants in full-length and active in its native trimeric form, stabilized with the LMNG detergent.

Purification: affinity chromatography
