This product is FOR RESEARCH USE ONLY. For commercial use, please contact partnerships@abcam.com.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

Our Low endotoxin, azide-free formats have low endotoxin level (1 EU/mg, determined by the TAL assay) and are free from azide, to achieve consistent experimental results in functional assays.

Activity summary

The CD16a protein also known as Fc gamma receptor IIIa (FcγRIIIa) plays an important role in the immune system. This receptor is about 50-70 kDa in mass and is expressed on the surface of natural killer (NK) cells macrophages and some T cells. CD16a facilitates antibody-dependent cellular cytotoxicity (ADCC) by binding to the Fc region of immunoglobulin G (IgG). This interaction allows effector immune cells to recognize and destroy antibody-coated target cells.

Biological function summary

CD16a is important for immune responses and occurs as part of a receptor complex. It signals downstream effects through its association with the CD3 zeta chain and the Fc epsilon receptor gamma chain which possess immunoreceptor tyrosine-based activation motifs (ITAMs). Upon binding to IgG CD16a triggers a cascade of events leading to the release of cytokines and cytotoxic granules. This action helps in eliminating infected or cancerous cells demonstrating its role in both innate and adaptive immunity.

Pathways

CD16a contributes significantly to the immunological synapse formation and NK cell activation pathway. This receptor cooperates with other proteins such as CD3 and CD19 to modulate the immune response. It also participates in signaling pathways like the PI3K-Akt pathway which regulates cell survival and proliferation. CD16a's interaction with these pathways highlights its importance in immune cell communication and function.

Associated diseases and disorders

CD16a is linked to autoimmune diseases and certain cancers. In autoimmune disorders like systemic lupus erythematosus (SLE) abnormal CD16a function can contribute to the pathogenesis by altering immune cell targeting. Additionally in cancers such as lymphoma CD16a's interaction with IgG-coated cancer cells can influence the efficacy of monoclonal antibody therapies. The receptor's association with proteins like CD3 and CD19 in these disease contexts highlights its potential as a therapeutic target.
