COVID-19 Spike Protein mRNA (N1-Me-Pseudo UTP) is an mRNA encoding the SARS-CoV-2 spike protein with enhanced performance via chemical modification. COVID-19 Spike Protein mRNA (N1-Me-Pseudo UTP) replaces natural uridine (UTP) with N1-Me-Pseudo UTP, which effectively reduces immunogenicity and improves stability and translation efficiency. The 3' UTR of COVID-19 Spike Protein mRNA (N1-Me-Pseudo UTP) optimizes AU-rich elements through HuR anchor sites, exhibiting higher translation efficiency. COVID-19 Spike Protein mRNA is widely used in COVID-19-related scientific research and vaccine development .

3-Methyluridine (m 3U; N3-Methyluridine) is a methylated nucleotide present in ribosomal RNA (rRNA), mainly targeting specific base sites of RNA molecules such as 23S rRNA. 3-Methyluridine can introduce a methyl group at the N3 position of uracil, affecting the secondary structure stability and base pairing ability of RNA, and regulating ribosome function. For example, it affects ribosomal subunit binding and tRNA interaction. 3-Methyluridine is often used as a key raw material for the synthesis of modified nucleotides, and is used to construct RNA oligonucleotides containing methylation modifications to study the effects of RNA methylation on gene expression and drug resistance .

2A3 (2-aminopyridine-3-carboxylic acid imidazolide) is a covalent probe reagent for Selective 2'-Hydroxyl Acylation analyzed by Primer Extension (SHAPE) that targets the RNA ribose 2'-OH group. 2A3 efficiently permeates the biological membranes of Gram-negative bacteria, Gram-positive bacteria, and mammalian cells. 2A3 exhibits no base bias and specifically labels conformationally flexible, unpaired regions within RNA. 2A3 forms covalent adducts by acylating the 2'-OH groups of flexible RNA residues. When combined with SHAPE-MaP (mutational profiling) sequencing technology, these modification sites are converted into detectable mutational signals, thereby accurately reflecting local RNA backbone flexibility and base-pairing status. 2A3 is primarily utilized in molecular biology and transcriptomics research, including the resolution of RNA structuromes in living cells, the study of RNA folding regulatory mechanisms, and the investigation of non-coding RNA functions .

Fmoc-(R)-2-(7-octenyl) Ala-OH is an unnatural Fmoc-protected amino acid and modification module. Fmoc-(R)-2-(7-octenyl) Ala-OH serves as a key building block for all-hydrocarbon cross-linking modification of antimicrobial peptides, and facilitates the generation of stapled peptide derivatives. When introduced into specific sites of the parent peptide, Fmoc-(R)-2-(7-octenyl) Ala-OH effectively increases the α-helix content of the peptide chain, thereby significantly enhancing its antimicrobial activity and proteolytic stability. Fmoc-(R)-2-(7-octenyl) Ala-OH is widely used in research on bacterial infections and the development of related antimicrobial agents . Stapled peptide is a specially chemically modified polypeptide. It locks the peptide chain into a stable α-helical structure by introducing a "staple"-like chemical bridge (usually an all-carbon backbone) at specific positions of the peptide chain.
