• Can you help me to pool my peptide after peptide library synthesis?

  As a complement to our peptide library service, GenScript can prepare customized peptide pools according to your customized specifications with pre-pooling LC-MS validation, and post-pooling marker validation QC options.

• What's the package available for peptide pooling?

  You can choose from 2 flexible package options:

  Package	Deliverables
  PepPool Standard	COA, MS, and HPLC validation data for each peptide before pooling Lyophilized pool(s) delivered 96-well plate or 100-tube rack Free aliquoting (up to 10 vials)
  PepPool Plus	COA, MS, and HPLC validation data for each peptide before pooling LC-MS on marker peptides (up to 8) in final pool to guarantee presence of all peptides within the final pool Lyophilized peptides in specified pool(s) delivered in a 96-well plate or 100-tube rack Free aliquoting (up to 10 vials)

  Note:*Single non-pooled peptides can be supplied upon request.
