If the lymph node or similar tissue is reactive, or otherwise benign, it should possess a mixture of kappa positive and lambda positive cells. If, however, one type of light chain is significantly more common than the other, the cells are likely all derived from a small clonal population, which may indicate a malignant condition, such as B-cell ...
There are approximately twice as many kappa-producing plasma cells as lambda plasma cells. Kappa free-light chains are normally monomeric, while lambda free-light chains tend to be dimeric, joined by disulphide bonds. Polymeric forms of both types of free light chain can also occur. [6]
The Lambda2 method, or Lambda2 vortex criterion, is a vortex core line detection algorithm that can adequately identify vortices from a three-dimensional fluid velocity field. [1] The Lambda2 method is Galilean invariant , which means it produces the same results when a uniform velocity field is added to the existing velocity field or when the ...
Defects in the CD43 molecule are associated with the development of Wiskott–Aldrich syndrome. [8] It also appears in about 25% of intestinal MALTomas. [citation needed] Using immunohistochemistry, CD43 can be demonstrated in the paracortical T-cells of healthy lymph nodes and tonsils; it is also positive in a range of lymphoid and myeloid tumours.

If the red cells then agglutinate, the test is positive, a visual indication that antibodies or complement proteins are bound to the surface of red blood cells and may be causing destruction of those cells. The indirect Coombs test is used in prenatal testing of pregnant women and in testing prior to a blood transfusion.

Mixed lymphocyte reaction (MLR) is a test used by pharmaceutical and biotech organizations to show the safety of a drug or implantable material. It is commonly used as part of the FDA clearance process. [1] Put simply, it is mixing populations of T-lymphocytes (category of white blood cells) together, and measuring the reaction that occurs.
