SUMMARY AND EXPLANATION
Human lymphocytes may be classified in three main populations according to their biological function and their cell surface antigen expression: T lymphocytes, B lymphocytes and Natural Killer cells (NK). B lymphocytes are the producers of antibodies and mediate humoral immunity particularly effective against toxins, whole bacteria, and free viruses. Most B cells, with the exception of pre-B progenitors, pre B-cells, and mature plasma cells, express immunoglobulin on their surface. Each cell expresses only one light chain type (Kappa or Lambda). In normal peripheral blood and lymph nodes, there is a mixture of Kappa positive and Lambda positive cells, with two-thirds of the cells expressing Kappa and one-third expressing Lambda. Since lymphoid neoplasms are usually clonal expansions of a single cell, malignant cells uniformly express the same Light Chain isotype. Neoplastic B cell lymphoprolipherative disorders can frequently be suspected based on the demonstration of a marker predominance of cells expressing a single Light Chain type. The Lambda immunoglobulin Light Chain count is generally expressed as a percentage of B cells present in the sample which can be determined by FC based on its positive expression of CD19.
APC-C750TM is a tandem dye with a maximum emission peak at 779 nm, which grants bright signal, low unspecific noise and high photostability. When excited by light from a red laser, the APC fluorochrome can transfer energy to C750 molecule, which then emits at a longer wavelength. It is recommended to use a 780/60 nm longpass filter along with a red sensitive detector to use in conjunction antibodies conjugated with APC and APC-C750TM.
