Upon request, Royobiotech Co.,Ltd can aliquot part or all of your order into smaller quantities for a minimum fee of $3 per tube. Aliquoted products are more expensive but may save you time, effort and money during determination of peptide solubility. Your peptides will also be more stable because they will not be exposed to as many freeze-thaw cycles, as many openings and closings of the container, mishandling, or bacterial contamination. Peptide oxidation, degradation, and aggregation are less prevalent in aliquoted samples.
