Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

Phospho-PLD1 (Ser561) Antibody detects endogenous levels of PLD1 only when phosphorylated at serine 561. This antibody does not cross-react with phosphorylated PLD2.

Phospho-PLD1 (Ser561)抗体识别内源性的Ser561磷酸化的PLD1蛋白。此抗体不与磷酸化的PLD2蛋白交叉反应。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser561 of human PLD1. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from C6 cells, untreated or PMA-stimulated for the indicated times, using Phospho-PLD1 (Ser561) Antibody (upper) or PLD1 Antibody #3832 (lower).

对未处理或PMA处理适当时间的C6细胞抽提物,使用Phospho-PLD1 (Ser561)抗体(上图)或PLD1抗体#3832(下图)进行Western blot分析。


Phosphatidylcholine-specific phospholipase D (PLD) hydrolyzes phosphatidylcholine (PC) to produce choline and phosphatidic acid (PA). PA is the precursor of the second messenger, diacylglycerol (DAG). Two isoforms of PLD (PLD1 and PLD2) have been identified so far. Both are regulated by protein kinases, small GTPases and Ca2+ (1). PLD1 is phosphorylated at Ser2, Ser561 and Thr147 by PKC (2,3). Phosphorylation at Thr147 and Ser561 regulates PLD1 activity (3).
