Site-specific crosslinking of antibodies

Methods are provided for making bispecific antibodies and antibody conjugates comprising site-specifically cross-linking two or more antibodies, antibody fragments or Fc-fusion proteins. Also provided are compositions and uses for the bispecific antibodies and antibody conjugates. The bispecific antibodies may be used to treat a disease or condition. Also provided are methods for site-specifically conjugating a liposome, an mRNA or an siRNA to an antibody, and uses of the antibody-conjugated liposome, mRNA or siRNA.

ANTI-CD276 MAB TO TARGET BREAST CANCER
20240279337 · 2024-08-22 ·

Disclosed herein is anti-human CD276 mAb expressing the Fc-fused fragments from the extracellular domain of human CD276 (Leu29-Pro245), producing the N-glycosylated peptides as immunogen, and generating hybridoma cells through fusing mouse splenocytes and myeloma cells. The specific targeting of cancer cells and intracellular release of potent drugs enables high anti-cancer efficiency and minimal side effects.

Treating bladder tumor cells using fibronectin attachment protein as a target

Composition and methods are disclosed for utilizing microaggregation of FAP-containing complexes to promote their fast internalization. This approach allows the uptake of cytotoxic cargo coupled to either FAP-Antibodies or FAP-liposome complexes by tumor bladder cells. Importantly, this approach is efficient even under serum-free conditions such as the ones found in the lumen of the bladder.
