Phospholipase D (PLD) is a key player in phospholipid metabolism. PLD hydrolyzes the phosphodiester bond of the glycerophospholipids, resulting in the production of phosphatidic acid and a free headgroup. PLD activity regulates the actin cytoskeleton, vesicle trafficking for secretion and endocytosis, and receptor signaling. Abnormalities in PLD activity and expression have been associated with Alzheimer's disease, stroke, cancer and other brain disorders. BioVision’s Phospholipase D Activity Assay Kit provides a simple and sensitive method of measuring PLD activity using colorimetry (OD 570 nm). In this assay, PLD cleaves choline from Phosphatidylcholine. The free choline is then oxidized by PLD enzyme mix to generate an intermediate which reacts with PLD Probe to generate color (OD 570 nm). This high-throughput adaptable assay kit can detect PLD activity as low as 1.0 mU/ml in a variety of samples.

What is the source of the positive control?
It is phospholipase D from a bacterial source.
Can we use frozen samples with this assay?
We would recommend using fresh samples. However, frozen samples can be used too provided they have not undergone multiple freeze thaw cycles.
Can the kit work on bacteria or yeast cells?
The kit has been standardized for mammalian cells only.
What is the exact volume of sample required for this assay?
There is no specific volume we can recommend for the amount any sample to be used since it is completely sample concentration and quality based. You have to do a pilot expt with multiple sample volumes to determine the optimal volume which gives a reading within the linear range of the standard curve. Please refer to the citations for this product to see what other clients have used with similar sample types.
Do you have trial sizes of this kit?
Unfortunately, we do not have trial sizes of this kit available. However, if you are based in the US or Canada, we will give you a 10% off list price introductory discount on its purchase price. If you are based out of this area please contact your regional BioVision distributor.
What is the shelf life of this kit?
BioVisions’s assay kits expire 6-12 months from the date of shipment. Some components of the kit may expire sooner as mentioned in the data sheet.
Can we purchase individual components of this kit?
Yes, you can purchase any of the kit's components without the whole kit. Please refer to the component Cat #s mentioned on the datasheet for ordering.
Can we use an alternate buffer for sample preparation (cell lysis, sample dilutions etc)?
Our assay buffers are optimized for the reactions they are designed for. They not only contain some detergents for efficient lysis of your cells/tissue, but also contain some proprietary components required for the further reactions. Therefore, we highly recommend using the buffers provided in the kit for the best results.
