Product details

Human MASP1 Antibody Pair is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify Human MASP1 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

Supplementary information

The MASP1 protein also known as mannan-binding lectin serine protease 1 or MASP-1 is a serine protease with a mass of approximately 76 kDa. It is mainly expressed in the liver and is secreted into the blood. MASP1 is an important component of the lectin pathway of the complement system. This protein is an enzyme that circulates in the blood in an inactive form and becomes active when it binds to pathogen surfaces linked to mannose-binding lectins or ficolins.
Biological function summary

MASP1 plays a vital role in the innate immune system by activating the complement cascade. MASP1 works as part of a complex made up of pattern recognition molecules and other proteases. On binding to pathogens the complex undergoes conformational changes that activate MASP1. This activation leads to the cleavage of downstream substrates including MASP-2 and complement component C4 triggering a series of enzymatic reactions that enhance the pathogen clearance by opsonization and lysis.

Pathways

MASP1 is heavily involved in the lectin pathway one of the three activation pathways of the complement system. It shares functional ties with MASP-2 which continues the cascade after MASP1 activates the pathway. While the lectin pathway runs parallel to the classical pathway it is distinguished by the nature of its initiating molecules that recognize carbohydrate patterns on pathogen surfaces without needing antibodies. MASP1’s role is critical in facilitating the initial steps of this process which eventually leads to the activation of the terminal complement pathway components.

MASP1 shows connections to immune-related conditions such as systemic lupus erythematosus (SLE) and infectious diseases. Its dysregulation or deficiency can impact the complement system leading to immune complex diseases like SLE due to the failure in clearing immune complexes effectively. Furthermore MASP1’s association with MASP-2 also makes it relevant in studies focused on lectin pathway deficiencies that result in increased susceptibility to infections highlighting its significance in maintaining host immunity.

Target data

Precursor of a serum protease that activates the complement 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.. Isoform MASP-1. Serine protease that activates 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 : 10946292, PubMed : 11527969, PubMed : 12538697, PubMed : 22691502, PubMed : 22966085, PubMed : 9087411). The lectin complement system is activated following association of lectins, such as MBL2, FCN1, FCN2 or FCN3, to carbohydrates on the pathogen surface (PubMed : 22854970, PubMed : 22966085, PubMed : 23386610, PubMed : 9087411). Following autoproteolytic processing in response to lectin-binding to pathogen carbohydrates, catalyzes cleavage and activation of MASP2, the next component of the lectin complement pathway (PubMed : 22691502, PubMed : 22966085, PubMed : 23386610).. Isoform MASP-3. Serine protease that activates the alternative 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 : 20038603, PubMed : 23792966, PubMed : 27535802). The alternative complement pathway acts as an amplification loop that enhances other complement pathways (PubMed : 27535802). Isoform MASP-3 specifically catalyzes cleavage and activation of factor D (CFD), the protease that initiates the alternative complement pathway (PubMed : 20038603, PubMed : 27535802).
