Packaging: LDL is membrane filtered and aseptically packaged in a solution containingphosphate-buffered saline at pH 7.4 and 0.2 mM EDTA-Na2.

Preparation: Human Low Density Lipoprotein, LDL, (Cat. No. AC11962) is isolated from blood bankproduced human plasma. It is purified via ultracentrifugation to homogeneity determined by agarose gelelectrophoresis. Each lot is analyzed on agarose gel electrophoresis for migration versus LDL. LDL is alarge protein (MW 3,500 kDa) with a diameter of 25.8 nm.It is composed of approximately 20-25%protein and 75-80% lipid. The lipid portion can be further described as 9% free cholesterol, 42%cholesteryl ester, 20-24% phospholipid, and 5% triglyceride.

Purity： 98%, is determined agarose gel electrophoresis .

Specifications： 0.22 micron filtered; Aseptically Filled; Cell Culture Tested.

Storage & Stability： This product is stable for 6 weeks after receipt when handled aseptically andstored at 2-8°C. NEVER FREEZE.

*Special Note： After prolonged storage, some precipitate may be observed. This is normal for thisproduct. Clarify out the aggregates by spinning in a microfuge for 2 minutes.

Biological Activity ： Sample lots of Acmec LDL are evaluated for receptor binding to peritonealmacrophages in conjunction with our DiI-Ox-LDL and [I-125] Ox-LDL .

*Preparations of LDL are fairly unstable; plan your experiments in advance and use fresh material. FOR RESEARCH USE ONLY
