Frequently Asked Questions

For certain services, if protein expression fails, clients may be charged 50% of the project cost to cover the expenses already incurred. Guaranteed expression services include multiple strategies to ensure success, minimizing the risk of failure.

We can synthesize peptides up to 30 amino acids for standard orders, with scales ranging from 1 mg to 1 g for lab-scale projects, and up to 1 kg or more for large-scale/bulk synthesis.

Peptides can be provided at purity levels from 75% to 98%, allowing you to select the optimal balance between cost and experimental requirements.

Standard synthesis is optimized for peptides up to 30 amino acids. For longer sequences, complex modifications, or unusual amino acids, we recommend consulting with our team for customized solutions.

Depending on the service, some antibodies are provided as purified protein ready for use, while others, like plate supernatant antibodies, may require additional purification before sensitive applications.

The main differences are in quantity, turnaround time, and QC standards:

Standard Recombinant Antibody Expression: Designed for research-scale production (3 mL – >1 L). It has a fixed 2-week turnaround and high QC standards (SDS-PAGE >95%, HPLC >95%, Endotoxin <1 EU/mg). This service is ideal when the primary goal is rapid, small- to medium-scale antibody production.

Guaranteed Recombinant Antibody Expression: Provides a guaranteed yield (10–1000 mg) and a slightly longer turnaround (2–5 weeks). QC standards are also high (SDS-PAGE >95%, HPLC >90%, Endotoxin <1 EU/mg), but this service is specifically suitable when a precise amount of antibody is required for experiments or downstream applications.
