H-TYR-GLY-ARG-LYS-LYS-ARG-ARG-GLN-ARG-ARG-ARG-OH

Description:

The chemical substance with the name "H-TYR-GLY-ARG-LYS-LYS-ARG-ARG-GLN-ARG-ARG-ARG-OH" and CAS number "191936-91-1" is a peptide composed of a sequence of amino acids, specifically including tyrosine (Tyr), glycine (Gly), arginine (Arg), lysine (Lys), and glutamine (Gln). This peptide is characterized by its basic nature due to the presence of multiple arginine and lysine residues, which contribute to its positive charge at physiological pH. The sequence suggests potential roles in biological processes such as signaling, cell adhesion, or immune response, as peptides with such compositions often interact with various biological receptors. The presence of a hydroxyl group at the C-terminus indicates that it is a peptide with a free carboxyl group, which can influence its solubility and reactivity. Additionally, the specific arrangement of amino acids can affect its conformation and biological activity, making it a subject of interest in fields such as biochemistry and pharmacology.

TAT (47-57) TFA salt

CAS: 191936-91-1

Amino acids 47-57 of the Human Immunodeficiency Virus (HIV) viral coat trans-activator of transcription protein (TAT protein). TAT is a cell penetrating peptide meaning it has the ability to transport itself across cell membranes and into a cell's nucleus independently. Cell penetrating peptides (CPPs) can be used to carry other molecules into the cell and therefore can be used in many applications. Such applications may include: drug delivery, where small drug peptides or nucleic acids can be delivered into target cells or where CPPs are conjugated to imaging agents such as fluorescent dyes or radiolabeled molecules they can be used for in vivo or in vitro imaging in diagnostics. 
This product is available as a trifluroacetate salt.

TAT (47-57)

CAS: 191936-91-1

Tat (47-57) is a cell penetrating cationic peptide derived from the N-terminus of the Tat protein, which is a trans-activator of the transcription protein present in the human immunodeficiency virus (HIV). Specifically TAT (47-57) is located within the arginine-rich basic domain 48-60 of the TAT peptide which as a whole has three domains which function to aid HIV through transactivation, DNA binding and nuclear transport. As a cell penetrating peptide (CPP) TAT aids in the cellular uptake of molecules and hence serves a valuable purpose in transduction methods. This property has been demonstrated through its ability of allowing toxins such as the neurotoxin Botulinum neurotoxin Type A, produced by the Clostridium botulinum type A bacteria to penetrate the skin barrier non-invasively. Additionally TAT (47-57) can be used to deliver proteins, fluorophores, chelators and DNA to target cells.
