Background :
Rabbits were immunized with a unique peptide derived from the human lysophospholipid phosphatase 2 protein.
Source :
Phosphatidic acid phosphatase type 2 (PAP2) was originally identified as a plasma membrane enzyme that catalyses the dephosphorylation of the putative second messenger, phosphatidic acid (PA) to diacylglycerol (DG) [1]. Subsequently, multiple isoforms of PAP2 were cloned [2-5]. It was found that these enzymes dephosphorylate a number of lipid phosphates in vitro other than PA, including the potent bioactive lipids, lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P). Therefore, they have been renamed lipid phosphate phosphatases (LPPs). Currently, there are four members of this family called LPP1, LPP1a, LPP2 and LPP3 [6]. S1P [7] and LPA [8] regulate the proliferation, differentiation, apoptosis and migration of cells by binding to a family of G protein-coupled receptors. Thus, EDG1/S1P1, EDG3/S1P3, EDG5/S1P2/AGR16/H218, EDG6/S1P4 and EDG8/S1P5/nrg-1 are high affinity S1P receptors [7] whereas EDG2/LPA1, EDG4/LPA2 and EDG7/LPA3 have high affinity for LPA [8]. Recently, the over-expression of LPP1 was shown to limit LPA-stimulated signalling in Rat2 fibroblasts [9] and LPA-stimulated DNA synthesis in HEK 293 cells [10]. Similarly, over-expression of LPP1, LPP1a and LPP2 attenuate S1P-signalling to the p42/p44 mitogen activated protein kinase cascade [11].

Provided as solution in phosphate buffered saline with 0.08% sodium azide Product Form: Unconjugated Purification Method: Ammonium Sulfate Precipitation Concentration: See vial for concentration
Specificity :
Applications :
This antibody can be used for Western blotting (10-15 µg/ml). Optimal concentration should be evaluated by serial dilutions. NOTE: Boiling LPP2 with sample buffer will aggregate the protein. Lysates should be prepared by mixing cells with lysis buffer (possibly with extra detergent) to solubilize the protein before adding sample buffer and lysate SHOULD NOT be boiled/heated. Functional Analysis: Western Blotting Positive Control: Transfected HEK-293 cells
Storage :
Product should be stored at -20°C. Aliquot to avoid freeze/thaw cycles Product Stability: See expiration date on vial Shipping Conditions: Ship at ambient temperature, freeze upon arrival
