Cat. No.

HYB 131-01

Product name

Anti-MBL (human)

Description

Mouse monoclonal antibody

Specificity

HYB 131-01 is specific for MBL (mannan-binding lectin) from human serum or plasma.

Immunogen

MBL purified from human donor plasma 

Application

ELISA, WB, IHC-P, IHC-F

Species reactivity (positive)

Human

Species reactivity (negative)

Not determined

Subclass

IgG1/k

Gene ID

4153

Clone number

3B6

Epitope

The epitope is on the head-neck region of the MBL protein chain. Prior binding of the antibody is thought to block binding to carbohydrate. The epitope differs from that of HYB 131-10 and HYB 131-11. 

Content

Available in 200 µL and 1 mL size.1 mg/mL +/- 15%. See Certificate of Analysis for details.

Purification

Protein-A purified

Form

Liquid

Solvent

0.01 M phosphate buffer, pH 7.4, containing 0.5 M NaCl and 15 mM sodium azide

Storage

4-8ºC without exposure to light. No precautions necessary during handling.

Target

Mannan-binding lectin (MBL), also called mannose-binding lectin or protein, belongs to the C-type family of collectins, showing calcium-dependent binding to certain sugars (1). It consists of oligomers of triple-chain subunits and its binding and complement activating activities depend on its normal oligomerization. On binding to mannan-like microbial surface carbohydrates, MBL activates the complement system by means of its own lectin pathway, dependent on the MBL-associated serine proteases (MASPs). Because of the presence of different structural and promoter alleles in the population, 12% or more of the population have low concentrations (<50ng/mL) of normally oligomerized, functional MBL in plasma or serum.

Application 1

ELISA
HYB 131-01 is selective for normally oligomerized MBL when used as detection antibody in sandwich ELISA with HYB 131-01 coat (1).
HYB 131-01 can also be used in a manan assay, when coating with manan and using HYB 131-01B as the biotinylated detection antibody (2).

 

The calibration curve of a sandwich assay for MBL using HYB 131-01 as the capture antibody and HYB 131-01B as the biotinylated detection antibody.

Application 2

WB
In Western blotting, HYB 131-01 reacts with human MBL in both its oligomerized state and as single protein chain of 26 kDa. A dilution guideline of 1/1000 has proved successful (2).

Application 3

IHC
HYB 131-01 is also well suited for immunohistochemistry on human tissue samples, frozen or paraffin embedded, from (3, 4). Please consult www.proteinatlas.org
