Indicators
Immunoglobulin Light Chain Kappa is one of two Ig light chain types. Each Ig molecule is typically composed of two heavy chains and two light chains. Ig kappa light chains contain a variable and a constant region. Kappa light chains are encoded by multiple V, J, and C gene segments, which are separated in the genomes of cells undifferentiated with regard to antibody gene expression. Diversity in the kappa light chain V region arises during differentiation of an activated (kappa-type) antibody-producing B-cell from variable recombination of kappa V genes with kappa J genes and somatic point mutation, which plays a major role in antibody diversity. (from OMIM and NCI)
Indicators
Immunoglobulin Light Chain Lambda is one of two Ig light chain types. Each Ig molecule is typically composed of two heavy chains and two light chains but Ig lambda light chains contain a variable and a constant region. Lambda light chains are encoded by multiple V, J, and C gene segments, which are separated in the genomes of cells undifferentiated with regard to antibody gene expression. During differentiation of an activated (lambda-type) antibody-producing B-cell, diversity in the lambda light chain V region arises from variable recombination of lambda V genes with lambda J genes and somatic point mutation, which plays a major role in antibody diversity. (from OMIM 147220 and NCI)
Tests
The determination of the ratio of IgM positive class-switched memory B-Lymphocytes to class-switched memory B-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
A measurement of the IgM positive plasmablasts in a sample.
Tests
An immunoglobulins blood test measures the amount of immunoglobulins in your blood. Immunoglobulins are also called antibodies. Antibodies are proteins that your immune system makes to fight germs , such as viruses and bacteria . Your body makes different kinds of antibodies to fight germs in different parts of the body and at different stages of an infection.
Indicators
Interleukin-4 (153 aa, ~17 kDa) is encoded by the human IL4 gene. This protein is involved in the regulation of the expression of class II MHC molecules, Fc receptors and cell surface-bound immunoglobulins.

Research record from Clin Chim Acta, 2026-06-15. PMID 42297320.
Indicators
This gene is involved in repression of transcription. It plays a role in the formation of pre-plasma memory B cells and immunoglobulin-secreting plasma cells.
