4-Thiouridine (4-SU) is a photoactivatable ribonucleoside analog that is widely used for RNA analysis, including short-range RNA-RNA crosslinking and nascent RNA labeling. The crosslinking thio moiety is attached directly to the nucleotide base, thus 4-SU

RGD-4C is a arginine-glycine-aspartic acid peptide (ACDCRGDCFC) with integrin binding activity. The Arg-Gly-Asp (RGD) sequence serves as the primary integrin recognition site in extracellular matrix proteins, and peptides containing this sequence can mimic the recognition specificity of the matrix proteins. RGD-4C is a αv-integrin ligand, can conjugate with bioactive molecule to exert antitumor effects in animal models.

Interleukin-6 fragment (human) is a pleiotropic cytokine produced by lymphocytes and non-lymphocytes. The Interleukin-6 fragment (human) coding gene is located on human chromosome 7, with a length of approximately 5 kilobases. Interleukin-6 fragment (human) has potential applications in immune response, acute response, inflammation, tumors, and hematopoiesis.
