Acetylated LDL-SAP [IT-08, KIT-08]

a tool for eliminating cells that express microglia in primary cell cultures; targeted via acetylated human low density lipoprotein, eliminated via saporin

SKU: IT-08 Category: Quantity: Individual 25 ug, Individual 100 ug, Individual 250 ug, Individual 1 mg, Kit w/controls 25 ug, Kit w/controls 100 ug, Kit w/controls 250 ug | Host: human | Reactivity: rat | Conjugate: saporin | Usage: eliminates cells |

Acetylated-LDL-Saporin (acLDL-SAP) has been used effectively to eliminate microglia from primary cultures of rat hippocampal neurons, while having no deleterious effect on neurons or astroglia. After 24 hours exposure, 3 µg/ml of acLDL-SAP selectively kills more than 90% of microglia cells. acLDL-SAP is excellent for removing contaminating macrophages from primary cultures to determine their role(s) in autoimmune diseases and in degenerative diseases such as Alzheimer’s.

Acetylated LDL-SAP is a chemical conjugate of acetylated human low density lipoprotein and the ribosome-inactivating protein, saporin. It eliminates scavenger receptor-positive cells. This includes the macrophage and its relative, the microglia.

Acetylated LDL-SAP is available individually (Cat. #IT-08) or as a kit (Cat. #KIT-08) which includes Acetylated LDL-SAP and Saporin (Cat. #PR-01).

SIRT1 protects against microglia-dependent amyloid-beta toxicity through inhibiting NF-κB signaling.

Chen J, Zhou Y, Mueller-Steiner S, Chen LF, Kwon H, Yi S, Mucke L, Gan L (2005) SIRT1 protects against microglia-dependent amyloid-beta toxicity through inhibiting NF-κB signaling. J Biol Chem 280(48):40364-40374. doi: 10.1074/jbc.M509329200

Usage: To eliminate microglia in mixed cortical cultures, cultures were treated with either Ac-LDL-SAP at 3 ug/ml for 18 h or 5mM leucine methyl ester for 12 h. These agents selectively kill microglia in mixed cultures.

Targeted toxins in pain.

Wiley RG, Lappi DA (2003) Targeted toxins in pain. Adv Drug Deliv Rev 55(8):1043-1054. doi: 10.1016/s0169-409x(03)00102-9

Summary: The authors discuss the use of 'molecular neurosurgery' in the study of nociception. Applications using targeted toxins, which include immunotoxins, protein-toxin conjugates, or peptide-toxin conjugates, are illustrated. The authors describe the use of these molecules as research tools, as well as their potential for therapeutics. A helpful table is included that lists neuronal surface markers and class of cells targeted for each targeted toxin.
