Information needed: Amino Acid Sequence
Final Delivery: Target proteins, Plasmid (optional), Project report or QC report
01. Except for a smaller number of expression high risk proteins, most proteins are risk-free customization: there is no charge if there is no expression, without any upfront payments.
02. The number of amino acids is not restricted, and specific proteins need to be explicitly evaluated.
03. If, due to the protein’s intrinsic properties, the quality and purity do not meet the requirements after attempts and there is no need to deliver the protein, only the prepaid fee (if any) will be charged.
04. Strict quality control is enforced, with default internal toxin levels at <1 EU/μg and purity greater than 90% (some proteins can reach more significant than 95%). If the estimated purity is below 90% due to protein characteristics, this will be communicated during evaluation, and the customer can decide whether to continue.
