(or immunoglobulin).
More specifically, it can refer to:
- Immunoglobulin light chain
]A light chain is the small polypeptide subunit of an antibody . A typical antibody is composed of two immunoglobulin heavy chains and two Ig light chains.-In humans:There are two types of light chain in mammals,* lambda chain...
- Ferritin light chain
Ferritin light chain is a protein that in humans is encoded by the FTL gene.It is abnormally expressed in fetuses of both IVF and ICSI, which may contribute to the increase risk of birth defects in these ART....
