Product details:
Mouse MBL ELISA Kit (ab208343) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of MBL protein in cell culture supernatant, serum, plasma, tissue extracts, and cell culture extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse MBL with 19.7 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
MBL is a secreted calcium-dependent lectin involved in innate immune defense. MBL binds mannose, fucose and N-acetylglucosamine on different microorganisms and activates the lectin complement pathway. MBL binds to late apoptotic cells, as well as to apoptotic blebs and to necrotic cells, but not to early apoptotic cells, facilitating their uptake by macrophages.

Mannan Binding Lectin often referred to as MBL is an important player in the innate immune system. It is known alternatively as mannose-binding lectin or mannan-binding protein. The mass of MBL is approximately 32 to 34 kilodaltons and it is primarily produced in the liver. MBL circulates in the bloodstream where it can recognize patterns on the surface of pathogens such as bacteria and viruses through its lectin-binding domain. This recognition leads to the activation of other components that play roles in immune response.
Biological function summary
Mannan Binding Lectin serves a significant role in immune defense by binding to carbohydrate structures on pathogens. It is part of a complex known as the lectin pathway of the complement system one of three pathways that activate the complement system to enhance pathogen removal. MBL can activate through a series of proteases leading to opsonization cell lysis and inflammation which are vital responses to infection.
Pathways
Mannan recognition by MBL initiates the lectin pathway an essential component of the complement system. This pathway converges with the classical and alternative pathways to enhance the immune response. MBL works closely with MBL-associated serine proteases (MASPs) particularly MASP-1 and MASP-2 which cleave complement proteins resulting in pathogen opsonization and membrane attack complex formation. These actions are tightly regulated and ensure effective defense against invaders.
Deficiencies or polymorphisms in MBL can lead to increased susceptibility to infections and developmental complications of the immune system. Individuals with low MBL levels may experience recurrent respiratory infections or other bacterial infections due to inadequate complement activation. Moreover variations in the MBL protein have connections with autoimmune diseases such as systemic lupus erythematosus where MBL levels might influence disease severity. In these conditions altered interactions with other immune proteins like C4 and C3 may contribute to pathological responses.
