Academy Bio-Medical Company, Inc.

  • $128.00


Host Species: Sheep
Antigen: Human Apolipoprotein (a)
Specificity

Specifically binds to human Lp (a) and apo (a). No cross-reaction to apo B-100/48; mino to plasminogen (Cross-reactivity to plasminogen was removed by passing plasminogen-Sepharose™ affinity column). Dilution for immunoblot and ELISA range: 1,000 to 200,000.

Use:

The antibody can be used for detection of Lp(a) and apo (a) in human plasma and lipoproteins, using immunoassays or immunoblots.

Storage: -20°C for long-term storage, 4°C for short- term storage. Aliquot to avoid repeated freezing and thawing.

 

Importance

The Lipoprotein (a) [Lp(a)] structure is similar to that of low density lipoprotein (LDL), regarding size and lipid composition of the particles and the presence of apolipoprotein B-100 (apo B-100). In addition to apo B-100, Lp(a) has a second protein, apolipoprotein (a) [apo (a)], which the molecular weight of that glycoprotein varies widely from 400 to 700 kDa. (Maranhão et al., 2013)

Previous research has shown that apo (a) has a similar structure with plasminogen and contains a serine protease domain and two types of plasminogen-like kringle domains. (McLean et al., 1987) The plasma concentration of human lipoprotein[a], Lp[a], is highly correlated with coronary artery disease. (Gaubatz et al., 1990)
