→Fab fragment
| Line 17: | Line 17: | ||
The 'F' stands for fragment and the 'ab' stands for antigen binding. This is the region where antigen binding takes place. The Fab portion of an antibody is made up of the N-terminal domains of both the heavy and light chains. This domain of the antibody is called the variable (V) domain (VH on the heavy chain, VL on the light chain) because there is such high variability between antibodies in this area. This allows recognition of thousands of different antigens. | The 'F' stands for fragment and the 'ab' stands for antigen binding. This is the region where antigen binding takes place.

====Kappa/Lambda Ratios==== | |||
In all antibodies there are 2 light chain types, kappa and lambda. | |||
