| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

[Synthesis of a partially purified fragment of salmon calcitonin 1-16 using a phenylhydrazide protective group].[Pubmed:8498959]
Bioorg Khim. 1993 Feb;19(2):182-9.
The partially protected fragment Boc-Cys(Acm)-Ser(Bu(t))-Asn-Leu-Ser(Bu(t))-Thr (Bu(t))-Cys(Acm)-Val-Leu-Gly-Lys(Boc)-Leu-Ser(Bu(t))-Gln-Glu(OBu(t ))- Leu-OH of salmon calcitonin was synthesized by the segment condensation in solution. Segments were synthesized by the DCC/HOBt method in solution with phenylhydrazide as a semipermanent protecting group for the carboxyl function of the C-terminal residue. The phenylhydrazide group was removed by oxidation with air oxygen catalyzed by copper pyridine complexes under mild conditions. The segments were then condensed by the DCC/HOBt method according to the scheme (6 + 3) + (3 + 4). The proposed scheme makes it possible to product the partially protected fragment 1-16 of salmon calcitonin on the gram scale.
Protection of asparagine and glutamine during N alpha-Bpoc-based solid-phase peptide synthesis.[Pubmed:8740971]
Int J Pept Protein Res. 1996 Mar;47(3):209-13.
In this paper we describe the synthesis and properties of Bpoc-Asn(Trt)-OH, Bpoc-Asn(Trt)-OPfp, Bpoc-Gln(Trt)-OH and Bpoc-Gln(Trt)-OPfp. These derivatives are highly soluble in CH2Cl2 and can be coupled efficiently in solid-phase peptide synthesis. The peptides, acetyl-Ala-Phe-Asn(Trt)-Gly-Leu-Ala-O-Dbf-SH and Boc-Cys(Acm)-Ala-Phe-Gln(Trt)-Gly-Leu-Ala-O-Dbf-SH (where O-Dbf-SH is the peptide ester of 4-mercapto-6-hydroxydibenzofuran) were synthesized by stepwise solid-phase peptide synthesis using N alpha-Bpoc amino acids. We have observed that less than 0.1% of the trityl group is removed from the carboxamide of Gln and Asn during a standard 15 min N alpha-Bpoc deprotection in 0.5% TFA in CH2Cl2.
