CoV-2/COVID-19 Peptide Libraries from 21st Century Biochemicals
To help with the current pandemic and the need for rapid scientific progress to help stem this pandemic, we are offering the following peptide libraries and other peptide tools to rapidly advance the fight against COVID-19/SARS-CoV-2. Overlapping peptide libraries Spike “S” protein/orf2/2019-nCoV/USA-WA1/2020 Class I fusion protein, 1273 amino acids in length; binds the virion to its host cell receptor (ACE2 protein), mediating viral entry Overlapping peptide library – 16AA in length/11AA overlap – 253 peptides Library available as: Individual peptides - 5ug per well, in 2D bar coded tubes, 96 well format Matrix pooled peptides (2D pooling, 5ug/peptide per pool) Available as 4 pools x 63/64 peptides, 8 pools x 31/32 peptides, 16 pools x 15/16 peptides Nucleocapsid “N” protein/orf9/2019-nCoV/USA-WA1/2020 Nucleoprotein, 419 amino acids in length; packages the (+) strand viral genome RNA into a helical RNP (ribonucleocapsid) and interacts with M protein and NSP3 tethering the viral genome to the replicase-transcriptase complex Overlapping peptide library – 16AA in length/11AA overlap – 82 peptides Library available as: Individual peptides - 5ug per well, in 2D bar coded tubes, 96 well format Matrix pooled peptides (2D pooling, 5ug/peptide per pool) Available as 1 pool x 82 peptides, 2 pools x 41 peptides, 4 pools x 20/21 peptides Membrane “M” protein/orf5/2019-nCoV/USA-WA1/2020 Membrane glycoprotein, 222 amino acids in length; interacts with E, HE and S proteins; also interacts with N protein for packaging of the viral genome Overlapping peptide library – 16AA in length/11AA overlap – 42 peptides Library available as: Individual peptides - 5ug per well, in 2D bar coded tubes, 96 well format Matrix pooled peptides (2D pooling, 5ug/peptide per pool) Available as 1 pool x 42 peptides, 2 pools x 21 peptides, 4 pools x 10/11 peptides Please call us at 508.303.8222 or email info@21stcenturybio.com for more details!
