All peptides are purified as trifluoroacetate salts to the level specified by the customer. They are supplied in the form of a lyophilised powder. The results of the HPLC purification and Mass Spec QC are also supplied to customers. Standard delivery depends on the complexity of the project, but is typically a few weeks from receipt of order. Please note that we offer an express delivery option for customers that require their peptides on short time-scales (within two weeks from receipt of oder).
