Catalog # AL9101

A431 + Calyculin A (30min) Treated


Application / Dilution
WB20 μl/lane

Size 100 μl



Calyculin A is a serine/threonine phosphatase inhibitor that inhibits the activity of protein phosphatases PP1 and PP2A. Human carcinoma A431 cells treated with calyculin A for 30 minutes can undergo significant threonine phosphorylation, as shown by western blotting using anti-Phospho-Akt (Thr-34), cat.# AP1001, as compared to untreated, control cell lysates.

Confluent cultures of A431 cells were serum starved overnight. Cells were then either left untreated (Cat.# AL9001) or treated with Calyculin A at a final concentration of 100 nM for 30 minutes at 37°C (Cat.# AL9101). Cells were lysed in 1% SDS, 1.0 mM sodium ortho-vanadate, 1 mM sodium fluoride, 10 mM Tris (pH 7.4) buffer. Protein concentration was determined using the BCA method (Pierce) before diluting to final concentration and buffer.

Western blot analysis of A431 cells (20 µg/lane) serum starved overnight (lanes 1 & 3) and Calyculin A (100 nM) treated for 30 minutes (lanes 2 & 4). The blot was probed with anti-phospho-Akt (Thr-34) (lanes 1 & 2) or anti-Akt (lanes 3 & 4).

Cell Lysates are supplied at a concentration of 1 mg/ml in electrophoresis sample buffer (62.5 mM Tris pH 6.8, 2% SDS, 5% glycerol, 0.003% bromophenol blue, 0.9% β-mercaptoethanol). Store at –20°C. Do not boil or dilute. Stable for 1 year.

The products are are safely shipped at ambient temperature for both domestic and international shipments. Each product is guaranteed to match the specifications as indicated on the corresponding technical data sheet. Please store at -20C upon arrival for long term storage.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
