Customer Reviews

  • We strongly recommend Camide Bio's protein expression platform service to any research team facing challenges in the field of protein expression. This has been a model CRO service experience, and we look forward to establishing long-term and stable cooperative relationships in the future.

    Dr. S

  • The protein samples delivered were of high quality (high purity, high homogeneity, good activity), and came with complete and rigorous project reports, covering the entire process data from gene sequence to final product, key experimental steps, and optimization logic. These detailed documents not only ensure the reliability of the results but also provide valuable technical references for our future research.

    Mr. J**

  • We had access to a variety of expression systems and a well-established technical platform, which ensured the successful and efficient delivery of our project.

    Mr. XU**

  • KMD provided a tailor-made protein expression solution that fully met our specific research needs.

    Miss Y**

  • The technical team was highly professional, offering timely and effective support from experimental design to final result delivery.

    Miss X**

  • The protein expression was rapid, and the resulting proteins were stable and suitable for long-term use.

Frequently Asked Questions

Protein Expression Platform(FAQs)

  • Can you provide custom protein production?

    Yes. we have extensive experience handling custom projects. We are highly qualified in delivering high-purity, low-endotoxin proteins or antibodies. If you have a custom request, please don’t hesitate to contact us.

  • What if I can’t find the protein I need on your website?

    We regularly update our protein catalog every quarter. Please check our website frequently or fill out our custom service request form. Our team will get in touch with you to discuss your needs in detail.

  • Do you offer gene synthesis services?

    Yes, we offer comprehensive services ranging from gene synthesis to downstream protein expression and purification for all expression systems. Just provide your gene of interest, and we will take care of the rest.

  • Yes, we offer comprehensive services ranging from gene synthesis to downstream protein expression and purification for all expression systems. Just provide your gene of interest, and we will take care of the rest.

    We recommend diluting all proteins in the desired cell culture media to the required concentration, followed by sterile filtration through a 0.2 μm filter before applying to cell cultures.

  • Does KMD Bioscience provide codon optimization services?

    Yes, we offer codon optimization for all expression systems. Our optimization algorithms aim to enhance downstream protein expression efficiency through various strategies.

  • What is a “crystallography-grade” protein?

    Proteins intended for crystallization should be homogeneous and have a purity greater than 90%. Before crystallization, purity should be confirmed by HPLC or mass spectrometry (MS). Dynamic light scattering (DLS) analysis can help assess homogeneity but is not strictly required. The minimum amount of protein typically required for crystallization trials is 10 μg*300 μL.

  • Should the His-tag be placed at the N-terminus or C-terminus in cloning design?

    If your protein is of moderate size and you don’t plan to remove the tag, either the N-terminal or C-terminal is acceptable. For smaller proteins, placing the His-tag at the C-terminal is recommended to reduce degradation. If you intend to remove the tag enzymatically, placing it at the N-terminal helps minimize residual amino acids after cleavage.
