This HPLC method is suitable for analyzing peptide, protein, oligo (DNA and RNA), and their conjugate, separating the components according to the negative charges of the molecule. It is generally a mild and selective method for analyzing. Once a method is estabilished, the analytical method can be transferred for purification of the conjugates. A standard pdf file of the HPLC profile will be supplied.

Per sample charge:

1-4 samples: $120

5-10 samples: $100

After 10 samples: $80

Standard services is 1-3 days.

Sample submission for peptide, protein, oligo, and their conjugate:

1)      Dilute your samples in water to 1 mg/mL for peptide or protein, or 10-100 uM for oligo. Transfer minimum 50 μL of the diluted solution to a 500 μL micro-centrifuge tube. Label the vial properly.

2)      Ship your samples with packing material and shipping method that are suitable for your samples.

For analysis of conjugate, always ship a sample of un-labeled biopolymer for analysis at the same time.
