  • Product overview

    Abcam’s ERK1/2 (pT202/Y204) and ERK1/2 (Total) in vitro SimpleStep ELISA™ (Enzyme-Linked Immunosorbent Assay) kit is designed for the semi-quantitative measurement of ERK1/2 (pT202/Y204) and Total ERK1/2 protein in Human and mouse cells.

    The SimpleStep ELISA™ employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

  • Induction of ERK1/2 (pT202/Y204) phosphorylation in MCF-7 cells in response to EGF treatment. MCF-7 cells were cultured in 96-well tissue culture plates, serum starved and treated (10 min) with a dose-range of EGF before cell lysis. Data from quadruplicate measurements of ERK1/2 (pT202/Y204) are plotted and compared against Total ERK1/2 protein levels.

We are actually working on the preservation of rat pancreas from ischemia-reperfusion injury that occurs during the retrieval of the organ before a transplantation to a recipient. We are looking for strong ischemia markers and we know from literature that ERK is activated in rat lung at early time of cold ischemia before a decrease at longer time (Makoto I et al., 2004. Journal of Immunology).
We extracted cytoplasmic proteins from frozen pancreas that have undergo different time of cold ischemia : 0, 2, 4, 6, 8, 10, 12 and 18h. Proteins were extracted using an homemade lysis buffer (20mM Tris, 1mM EDTA, 1mM EGTA, 150 mM NaCl, 0.5% Triton-X-100 and a protease inhibitor cocktail (Complete™ ULTRA Tablets, EDTA-free, glass vials Protease Inhibitor Cocktail, Roche) and were frozen at -80°C. A BCA test was performed to determine proteins concentration in our sample and 70µg of pancreatic proteins were dilute in 50µl of 1X cell extraction buffer PTR for the assay. OD were read with Glomax from Promega.

We obtained concording results with literature : a decrease of ERK
activation with time of cold ischemia in pancreas. Moreover, western blotting of ERK with the same samples confirm this results.

1. Wash the 6 well plate with PBS after ultrasound exposure.
2. Lyse the cells with 0.5mL of freshly prepared Lysis buffer per well, with shaking (~300 rpm) at room temp for 10 minutes.
3. Aliquot supernatant (this is the soluble cell extract) to clean, chilled tubes on ice and store samples at -80°C. Minimize freeze/thaw cycles.
4. Determine desired number of microplate strips. Remove unused strips from frame and return to storage pouch and seal.
5. Add 50 μL/well of lysate to the microplate.
6. Add 50 μL/well Lysis Mix (negative control) and Control Lysates (positive control) to separate wells for assay controls if desired.
7. Add 50 μL/well of Antibody Mix to the wells. Cover the microplate with adhesive seal and incubate for 1 hr at room temp on a microplate shaker (400 rpm).
8. Wash wells with 350 μL/well 1X Wash Buffer (repeat 3 times). After final wash, remove any remaining wash solution from wells.
9. Add 100 μL/well TMB and incubate in the dark on a plate shaker set to 400rpm.
10. Add 100 µL/well Stop Solution, and mix briefly (1 min) on a microplate shaker.
11. Record the OD at 450 nm.

Very reliable, fast and easy ELISA kit.

Excellent Excellent 5/5 (Ease of Use)
I highly recommend this ERK SimpleStep ELISA kit. There’s a lot of ERK ELISA kit out there, but with this one you can record both total and phospho-ERK levels in less than two hours! Also it’s very reliable. I’ve used others before but they could take at least 5-6 hours to complete and I had to buy two kits one for total and one for phospho-ERK, it’s an advantage if you have few samples. I thought that I would need a lot of sample to get a decent signal in so few time, but I’ve recorded a strong signal (at least 1 OD) even with low concentrated samples (0,2mg/ml total protein), even with phospho-ERK. Stimulating with serum alone is enough to get a strong signal. On the other hand, in the blank well (both for total and phospho-ERK) the signal was almost the same as an empty well. I recommend using less sample with total ERK than with phospho-ERK or you could saturate the signal. In standard conditions, you can’t use all the plate with only one antibody, there are phospho-antibody for 60 wells and total antibody for 60 wells.
