Product details

Human Mannan Binding Lectin/MBL Antibody Pair - BSA and Azide free (ab288643) is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify Human Mannan Binding Lectin/MBL in sandwich ELISAs and many other pair-based applications.

Patented technology
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

The pair can be used in variety of assays and platforms including but not limited to:

  • Sandwich ELISA
  • FRET/TR-FRET/HTRF
  • Meso Scale Discovery® (MSD®)
  • Bead-based assays
  • AlphaLISA®/AlphaScreen®
  • DELFIA® immunoassays
  • Simoa® and Single Molecule Counting (SMC™) immunoassays
  • Multiplex

Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:

  • Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
  • Concentration of ~1 mg/ml as measured by the protein A280 method.

We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.

Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.

Please note:

The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.

The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.

We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

Antibody properties:

Capture antibody: recombinant rabbit monoclonal (unconjugated) – 100 µg

Detector antibody: recombinant rabbit monoclonal (unconjugated) - 100 µg

Concentration: ~1 mg/ml

Storage buffer: 100% PBS

Form: Liquid

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.

Target data

Calcium-dependent lectin, which acts as a pattern recognition receptor that initiates the lectin pathway of the complement system, a cascade of proteins that leads to phagocytosis and breakdown of pathogens and signaling that strengthens the adaptive immune system (PubMed : 14515269, PubMed : 22966085, PubMed : 7634089, PubMed : 9087411). Specifically recognizes and binds the mannose moiety of carbohydrates on the pathogen surface, activating the MASP1 serine protease and initiating the proteolytic cascade of the lectin complement pathway (PubMed : 22966085, PubMed : 2573758, PubMed : 6643429, PubMed : 8082295, PubMed : 9087411). Upon SARS coronavirus-2/SARS-CoV-2 infection, activates the complement lectin pathway which leads to the inhibition SARS-CoV-2 infection and a reduction of the induced inflammatory response (PubMed : 35102342). May bind DNA (PubMed : 15145932).
