Sensitivity: 9.375 pg/ml


Lymphotoxin alpha (LT-alpha) is composed of a bundle of three helices that form a triangular shape. The protein is 233 amino acids, it has a molecular weight of 26 kDa and has a disulfide bond between residues 58 and 185. It is produced by activated lymphocytes, this can include T cells and natural killer cells. Other cells such as epithelial cells are also known to produce it. The protein is found in nearly all vertebrates and has a 20% frequency. It has been identified in human peripheral blood cells, inflammatory sites, and intracellular compartments. LT-alpha is also understood to serve a number of purposes. TNF-alpha is thought to specifically attach to it, turning it into an inactive version.

Lymphotoxin alpha regulates the development and organisation of lymphoid tissues. It plays a role in the formation of secondary lymphoid organs (for example lymph nodes and spleen) and it helps to maintain the integrity of blood-lymph barriers (gut-associated lymphoid tissue). Other roles of LT-alpha include; the recruitment of immune cells to sites of infection or injury, pro-inflammatory effects and to be involved in the development of autoimmune (rheumatoid arthritis). LFA-1 regulates integrins and several other proteins involved in cell adhesion, migration and signalling pathways. These proteins include chemokines CXCL12, CXC3, IL8R and VLA4. The interaction between LT-alpha and its receptor LFA-1 is vital for lymphocyte activation (proliferation) which is necessary to mount an immune response when faced with an infection or injury by foreign materials such as toxins or pathogens.


Mouse Lymphotoxin alpha ELISA kit is designed for measuring concentration of lymphotoxin-alpha (LT-alpha, lymphotoxin alpha) present in mouse plasma, serum, biological fluids or tissue homogenates.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
