Clathrin independent endocytosis (CIE) is a form of endocytosis present in all cells that mediates the entry of nutrients, macromolecules and membrane proteins into cells. We have been using DMSO and making a stock solution of 30mM (with a view to using it at 1:1000 i.e. Cells were then exposed to BG-S-S-594 and allowed to internalize for 30 minutes at 37. I think heating the PBS would not affect the inhibitory activity but I have no data demonstrating that this is the case. Interferes with receptor mediated endocytosis (RME), entry of HIV and synaptic vesicle recycling. P-values were calculated from the raw data and compared between DMSO and different doses of pitstop 2. -, Sabharanjak S, Sharma P, Parton RG, Mayor S (2002) GPI-anchored proteins are delivered to recycling endosomes via a distinct cdc42-regulated, clathrin-independent pinocytic pathway. This fluorescence is not usually detectable if the cells have been first fixed and washed prior to imaging. 2012; 7(9): e45799. They also states that cell morphology is unaffected by an exposure of greater than 30 minutes. This same question applies for Pitstop 2. The product can be stored for up to 12 months. Our customer accidently stored this product at -20C instead of +4C for the past month. I have created a 30mM stock in DMSO; then added 1 ul of this stock (at room temp) to 1.2 mls cell culture medium (minimum essential medium); I mix and immediately I can see crystals form in the medium after adding the 1ul pitstop;Any idea what is going on and how to keep pitstop in solution? As a guide, for a stock solution of 30 mM, you would need to dilute a 5 mg pack into 352 ul of DMSO. Thank you for your inquiry. Novel, selective, cell membrane permeable clathrin inhibitor.

Please contact us with any other questions. One way to distinguish CIE from CDE has been to deplete cells of coat proteins involved in CDE such as clathrin or the dynamin GTPase, leading to a block of CDE but not CIE. A drawback of such genetic manipulations is that depletion of proteins important for mediating CDE over a period of days can have complex indirect effects on cellular function. Cell counting kit-8: rabbit from Dojindo. Endocytosis inhibitors pitstop ® 2 (general inhibitor of endocytosis), dynasore (dynamin inhibitor) and methyl-β-cyclodextrin (cholesterol chelator) inhibited the uptake of QAPB. Fluorescence recovery after photobleaching (FRAP) of surface SNAP-Tac was performed. As stated on page 7 of our protocol booklet for ab120687, longer incubation times (such as greater than 30 minutes) may lead to non-specific effects and are therefore not recommended. Cells were then allowed to internalize Alexa594-Transferrin and antibodies to MHCI in the presence or absence of the drug for 30 min and then processed as described in Figure 1. 2 0. On the next day, the cells were pretreated with either 30 μM Pitstop 2 or Dyngo 4a, diluted in RPMI-1640 full media, in the incubator for 2 h.

Thank you for contacting us. Related products Pitstop ® 2 ( ab120687 ), Pitstop ® 1 ( ab120686) and Pitstop ® 1-25 ( ab144651 ). The effects of pitstop 2 are not restricted to inhibition of clathrin since knockdown of clathrin fails to rescue the inhibition of endocytosis of CIE proteins by the drug. I'm worried that after washing out extracellular virus, I'll relieve the inhibition and virus that may be bound to cell surface receptors will then get into the cell via RME anyway. I hope that this has been helpful. D) Pitstop 2 does not interfere with AP-2-mediated cargo sequestration into CCPs. Thus pitstop 2 has additional cellular targets besides the amino terminal domain of clathrin and thus cannot be used to distinguish CIE from CDE.
