Fmoc-Arg(Pbf)-OH | CAS:154445-77-9 | 99% Purity Spot Supply

Protected amino acids are the most basic raw materials for solid-phase peptide synthesis . Amino acids all contain alpha amino and carboxyl groups, and some of the 20 amino acids also contain side-chain active groups, such as hydroxyl, amino, guanidino and heterocyclic groups. These active groups need to be protected during the peptide reaction, and the protective groups are removed after the target peptide is synthesized.The most frequently used protected amino acid raw material is the Fmoc amino acids

Fmoc-Arg(Pbf)-OH (CAS:154445-77-9) Fmoc arginine is a kind of Fmoc protected amino acid, which can be selected from reagent grade and industrial grade. The side chain of arginine is properly protected by Pbf group.The purity is 95-99%.

1. Peptides in the form of lyophilized powder provided can be stably transported under normal temperature through sealed packaging.Peptides requiring long-term preservation shall be stored in a sealed container containing desiccant in the form of lyophilized powder and stored at a temperature below - 20 centigrade, which can avoid peptide degradation, bacterial degradation and oxidation, and the formation of secondary structure of peptide.

2. The peptide has hygroscopicity. Before opening the package or weighing, please balance the peptide in the desiccator to room temperature to avoid the water absorption.Then can unfold the vial to weigh the peptide.

3. The dissolved peptide is much more unstable than the lyophilized form.The peptide in the form of solution should be dissolved in the sterile water of pH 5-7(or filter with 0.2 μ m membrane) and stored at - 20 centigrade.Stored in small amount respectively to avoid repeated freezing and dissolve of them.

4. Peptides containing Cys, Met or Trp are easy to oxidize. Before peptide sealing, we will add nitrogen or argon to reduce its effection of oxidation. Therefore, deoxidizing buffer is essential for dissolution.
