To assist research and pharmaceutical organizations in rapidly achieving efficient and reliable expression and purification of antibody fragments, Creative Biolabs offers a comprehensive range of advanced services, focusing on six distinct types of antibody fragments: Fab, scFv, Hexamer, BCR, TCR, and ScFv-Fc.
Nowadays, Creative Biolabs has developed an in vitro recombinant expression platform centered around mammalian cells, offering clients an array of high-quality services. Our solutions include sequence analysis, linker design, fusion tag design, high-expression vector construction, optimization of antibody fragments expression strategies, refinement of recombinant expression conditions, and antibody fragments purification.
Clients can supply antibody fragments according to their specific needs. Creative Biolabs possesses high-yield pCBT series vectors, along with 293 and CHO cell lines, enabling the efficient secretion and expression of various forms of antibody fragments. We use advanced technology and streamlined production processes to significantly enhance the yield and purity of antibody fragments, while also reducing production time. All products undergo rigorous testing with advanced equipment such as HPLC and Mass Spectrometry (MS) to ensure they meet industry standards.

In the past few years, the technology surrounding antibody fragments has gained significant attention due to its unique biological properties and potential applications in targeted therapies. Creative Biolabs is poised to offer clients comprehensive and expert preclinical contract research organization (CRO) services, with a focus on solutions for antibody fragment production. Our offerings encompass six distinct types of antibody fragments, each providing unique characteristics and applications, which we will explore in detail below:
Fab antibody fragments consist of the variable region of an antibody along with one light chain, retaining the advantages of high specificity and affinity. Our Fab fragment expression and purification services employ advanced yeast or cell expression systems to optimize both yield and quality. Additionally, we offer tailored purification processes to ensure the generation of highly pure Fab fragments, suitable for subsequent pharmacological and clinical studies. The application of Fab fragments is becoming increasingly widespread in neutralizing antibodies, diagnostic agents, and targeted therapies, presenting valuable collaboration opportunities for pharmaceutical companies.
ScFv are formed by linking the variable regions of antibody heavy and light chains through a peptide chain, allowing them to target antigens with a smaller molecular weight. We use efficient cell lines for scFv expression to ensure that the products are stable and fully functional. Furthermore, our purification process integrates various chromatography techniques to achieve optimal separation and purity. Our service is particularly important for clients looking to enhance their research pipelines, as scFv antibody fragments play a crucial role in applications such as in vitro diagnostics, drug screening, and ligand capture technologies.
We offer a wide range of services for the expression and purification of hexameric antibodies. These Hexamer antibodies exhibit enhanced stability and affinity, allowing them to maintain their active state in complex biological environments. Our team utilizes advanced recombinant protein production techniques to ensure the efficient generation of high-quality Hexamer antibodies. By optimizing culture media and expression systems, we deliver Hexamer antibodies with excellent biological activity, meeting the rigorous demands of drug development and fundamental research.
B cell receptors (BCRs) are critical immune molecules, and their study is essential for understanding immune responses and developing antibody therapeutics. Our BCR expression and purification service employs unique and effective methods to provide clients with functional BCRs. Utilizing specially designed expression systems, we ensure that BCRs are accurately folded and active in their natural state, thereby providing a reliable foundation for subsequent functional studies. Our service also includes customized expression and purification of various BCR subtypes, enabling clients to obtain specific antibodies tailored to their research needs.
Soluble T cell receptors (TCRs) play a vital role in cancer immunotherapy and vaccine development. We provide specialized services for the expression and purification of soluble TCRs. Through optimized expression systems and purification processes, we can efficiently produce functional TCRs, offering researchers ideal models for cell experiments and drug screening. Additionally, drawing on our extensive experience, we can deliver personalized TCR solutions that cater to specific research targets.
ScFv-Fc antibodies are a specialized class of recombinant antibodies formed by the fusion of scFv with the Fc region, combining the high affinity of scFv with the effector functions of the Fc portion. Based on our proprietary expression system and optimized purification process, we can efficiently produce scFv-Fc antibodies, ensuring higher expression levels and purity. Our services guarantee not only the biological activity of the antibodies but also offer various labeling and handling options to meet diverse experimental requirements. Additionally, our team provides tailored designs of expression constructs to align with specific client needs, ensuring that the produced scFv-Fc antibodies effectively target designated antigens.
