Product Summary for Human MBL Quantikine ELISA Kit
The Quantikine Human MBL immunoassay is a 4.5 hour solid phase ELISA designed to measure human MBL in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant human MBL and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human MBL showed dose-response curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values of naturally occurring human MBL.

Background: MBL
Mannose/mannan-binding lectin (MBL) is a secreted glycoprotein in the collectin family of pattern-recognition molecules. It contains a cysteine-rich region, a collagen-like segment, and a C-type lectin domain that binds to neutral bacterial carbohydrates. The collagen-like region mediates MBL association into disulfide-stabilized trimers which further associate into complexes containing three or four copies of the basic trimer. MBL is secreted by hepatocytes and opsonizes bacteria through interactions with microbial carbohydrates. MBL multimers can associate with the serine proteases MASP-1, -2, and -3 and promote their cleavage of Complement Component C3. Proteolytic cleavage of C3 triggers activation of the complement system and formation of the membrane attack complex, leading to destruction of opsonized bacteria. Opsonized apoptotic material is cleared by the scavenger receptor CD91.
