Description générale
Product Source: Human plasma, fresh, non-frozen. Tested negative for anti-HIV-1, anti-HIV-2, anti-HCV, anti-HBc and HBsAg.
Two forms of Apo B exist: Apo B-100 and Apo B-48. The first is found in VLDL and LDL and is produced by the liver. The second is found in chylomicrons and originates in the intestine.
Apo B is purified from LDL isolated by density gradient ultracentrifugation (1.03-1.05 g/mL density range) followed by size exclusion chromatography in 10 mM deoxycholate, 50 mM NaCl, 50 mM Na2CO3, pH 10 (Walsh & Atkinson 1983).
PROPERTIES:
Apo B, which has a Mr of 550 kD, is the major protein found in LDL and is responsible for the cellular uptake of LDL particles from the plasma (Goldstein & Brown 1982). The Apo B prepared by this procedure is aggregated. The aggregates are not retained by a 0.45 mm filter, but migrate only a short distance into a 5% SDS PAGE gel. In the isolation buffer, Apo B gives a stable solution that is slightly hazy.

Forme physique
Lyophilized from 50 mM Na2CO3, pH 10, 50 mM NaCl, and 10 mM sodium deoxycholate solution. Non-sterile.
Stockage et stabilité
Maintain lyophilized material at <= -20°C for up to six months. Reconstitute to 1 mL by adding deionized water. If the deoxycholate is removed, Apo B-100 will slowly aggregate and become insoluble. After reconstitution maintain at +2-8°C for up to 4 weeks.
Remarque sur l'analyse
Single arc by IEP against antisera to whole human serum.
