BiCell Scientific Inc has optimized hybridoma cell growth for monoclonal antibody secretion in continuous cultivation bioreactor with a chemically defined, serum-free culture medium (Cat No: BCMABK6). Continuous cultivation bioreactor permits monoclonal antibody secretion rate to reach 100-150 μg/ml medium, which is approximately 3-fold higher than that in adherent or suspension flasks.

Bioreactor Scale-up Service of Antibody Production can be used in conjunction with BiCell Scientific’s Transgenic Antibody Production Service (Cat No: BCFTIG), if customers have antibody sequences but not readily made hybridoma cells. Bioreactor Scale-up Service of Antibody Production includes affinity chromatography purification based upon Protein A, Protein G or Protein L column.

"I am really impressed with your approach. We tried multiple times previously to create monoclonal and polyclonal antibodies to claudin-2 and MLCK1. We have had limited success generating polyclonals and no success generating monoclonals. You have generated outstanding monoclonals to both. I look forward to continuing to work with you."

"The polyclonal antibody you generated for KIAA0408 is stunning! KIAA0408 is a novel cilium molecule that has never been studied. So, clearly there will be a lot of demand for it as we have discovered a very interesting finding and the story will be published in a high impact journal. I am strongly inclined to generate monoclonal antibody for this protein too and we should think about patenting it."

"Your ARL13B antibody works beautifully!!! We’re so happy to have a cilia-specific antibody made in rat! I can send you high resolution images to be posted on your website."

"The assay is a homophilic interaction mediated cell adhesion on purified protein (in this case, immobilized purified Pcdhga9 to Pcdhga9 expressed on cell surface). Compared to control, cell adhesion is reduced in the presence of Pcdhga9 monoclonal antibody supernatants!"

I have tested the rat polyclonal IgGs to ABCD1 by immunoflourescence on cells overexpressing ABCD1. The antibodies successfully detected the protein (either untagged or tagged with GFP) at a 1:500 dilution and there was little background. The antibodies did not detect ABCD2. So this is very good news, and you may now go ahead and clone out a monoclonal!
