Description of Glp-Amyloid-β (3-40) Peptide (human) (trifluoroacetate salt)

Glp-Amyloid-β (3-40) peptide is a fragment of amyloid-β (1-40) that contains the cyclic amino acid pyroglutamate at the N-terminus. Glp-Amyloid-β (3-40) peptide is a major component of the endogenous amyloid-β content in post-mortem brain tissue from patients with Alzheimer's disease.1 It is formed through cleavage of the N-terminal aspartate and alanine on Aβ40 and Aβ42 followed by dehydration of glutamic acid by glutaminyl cyclase.2 Glp-Amyloid-β (3-40) peptide has been used as a reference peptide for the quantification of total pyroglutamate amyloid-β in APP23 mouse brain.1

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
