31. What are antibody fragments?

The antibody molecule is modular and separate domains can be extracted through biochemical or genetic means.  Specific fragments of antibodies can be produced through recombinant processes.  Randox Life Sciences are able to offer three different sizes of fragments;  Single domain antibody fragments are the smallest fragment we offer at 15kDa,  Single Chain Variable Fragments (scFv’s ) at 30kDa, and the largest fragment we can generate is the fragment antigen-binding antibody at 60kDa.  

32. What are the main advantages of using these antibody fragments?

Antibody fragments have many potential advantages, due to their small size they can provide better tissue penetration, higher coating concentrations and bringing events closer to biosensor surfaces.  They can also be seen to have a higher affinity and sensitivity, there is also less assay interference due to the removal of the Fc region.  

33. How does Randox Life Sciences manufacture these products?

As mentioned previously, fragments are produced through recombinant processes, most commonly they are expressed in secondary hosts such as E.Coli, yeast or Chinese Hamster Ovarian (CHO) cells. 

As the chains are genetically engineered they can be easily adapted and altered for use in specialised applications for example , Randox Life Sciences have pioneered a specialised proprietary functional expression tags which are designed to aid directed immobilisation and conjugation of fragments for use as capture and detection ligands in biochip-based assays. 

Fragments can also be processed through rounds of affinity maturation to increase their functional sensitivities and can be expressed in higher valency formats as dimeric, trimeric and tetrameric fragments in order to increase their functional avidity.
