Recombinant Antibody Expression Services

Recombinant antibodies are genetically engineered to generate specific antibodies within host cells. They are commonly utilized in medical research, diagnostics, and therapeutics. In comparison with traditional hybridoma antibodies, recombinant antibodies can be produced rapidly and in large quantities, featuring higher specificity and consistency. This is achieved by directly employing antibody gene sequences without the need for immunization and screening.
Utilizing a mammalian cell recombinant expression platform, MCE has devised practical methods and tools for expressing recombinant monoclonal antibodies targeting antibody sequences, aiming to achieve high yields, high purity, and low endotoxin levels. In addition to expressing full-length antibodies, MCE can also produce various types of recombinant antibodies, such as Fab, scFv, VHH, fusion proteins, chimeric antibodies, and bispecific antibodies. MCE's recombinant antibody expression services encompass codon optimization, vector construction, expression, purification, and QC analysis. All you need to do is provide the sequence information of the antibody (or VH/VL) to MCE. We are dedicated to providing high-quality recombinant antibodies to assist your research endeavors.
