Comment

Simultaneously measure Phosphorylated protein and pan protein in one experiment (for normalization purpose)
Screen numerous different cell lysates without performing a Western Blot analysis
Minimal hands-on time, convenient, and non-radioactive material

Plate Pre-coated,Strips (12 x 8)
Protocol Phospho-Stat1 (Ser727) and Pan Stat1 ELISA (Enzyme-Linked Immunosorbent Assay) kit is a very rapid, convenient and sensitive assay kit that can monitor the activation or function of important biological pathways in cell lysates. By determining phosphorylated Stat1 protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blot analysis.
This Sandwich ELISA kit is an in vitro enzyme-linked immunosorbent assay for the measurement of human phospho-Stat1 (Ser727) and pan Stat1 (help normalize the results of phospho-Stat1 from different cell lysate being compared). An anti-Stat1 (Ser727) (half plate, red marker on left side) and anti-pan Stat1 antibody (half plate, black marker on right side) has been coated onto a 96-well plate. Samples are pipetted into the wells and phosphorylated (left side) and pan (right side) Stat1 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated Stat1 is used to detect phosphorylated or pan Stat1. After washing away unbound antibody, HRP-conjugated Streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Stat1 (Ser727) or pan Stat1 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm. Phospho-Stat1 (Ser727) and pan Stat1 ELISA Kit Protocol 3 II.
Reagent Preparation 1. Bring all reagents and samples to room temperature (18 - 25 °C) before use.
2. Item E, Assay Diluent should be diluted 5-fold with deionized or distilled water before use.
3. Preparation of Positive Control: Briefly spin the Positive Control vial of Item K. Add 700 µL 1x Assay Diluent (Item E, Assay Diluent should be diluted 5-fold with deionized or distilled water before use) into Item K vial to prepare a Positive Control (P-1). Phospho-Stat1 (Ser727) and pan Stat1 ELISA Kit Protocol 6 Dissolve the powder thoroughly by a gentle mix (it can be removed by centrifuge if any precipitate in the solution is found). Pipette 260 µL 1x Assay Diluent into each tube. Use the P-1 to produce a dilution series (shown below). Mix each tube thoroughly before the next transfer. 1x Assay Diluent serves as the background.
4. If the Wash Concentrate (20x) (Item B) contains visible crystals, warm to room temperature and mix gently until dissolved. Dilute 20 mL of Wash Buffer Concentrate into deionized or distilled water to yield 400 mL of 1x Wash Buffer.
5. Briefly spin the biotinylated antibody (Item C) before use. Add 100 µL of 1x Assay Diluent into the vial to prepare a biotinylated antibody concentrate. Pipette up and down to mix gently (the concentrate can be stored at 4 °C for 5 days or at - 80 °C for one month). The biotinylated Stat1 antibody should be diluted 55-fold with 1x Assay Diuent and used in step 4 of Part VII Assay Procedure.
6. Briefly spin the HRP-Streptavidin concentrate vial (Item G) and pipette up and down to mix gently before use. HRP-Streptavidin P-1 P-2 P-3 P-4 0 130 µL 700 µL 1x Assay Diluent + Item K vial 130µ l 130 µL Phospho-Stat1 (Ser727) and pan Stat1 ELISA Kit Protocol 7 concentrate should be diluted 40 fold or 200 fold (see “step 6” in page 8 for detail) with 1x Assay Diluent. For example: Briefly spin the vial (Item G) and pipette up and down to mix gently . Add 150µl of HRP-Streptavidin concentrate into a tube with 6 mL 1x Assay Diluent to prepare a 40-fold diluted HRP-Streptavidin solution (don’t store the diluted solution for next day use). Mix well.
7. Cell Lysate Buffer should be diluted 2-fold with deionized or distilled water before use (recommend to add protease and phosphatase inhibitors). VII.
Sample Preparation Cell lysates - Rinse cells with PBS, making sure to remove any remaining PBS before adding the Cell Lysate Buffer. Solubilize cells at 4 x 107 cells/mL in 1x Cell Lysate Buffer (we recommend adding protease and phosphatase inhibitors to Cell Lysate Buffer prior to sample preparation). Pipette up and down to resuspend and incubate the lysates with shaking at 2 - 8° C for 30 minutes. Microcentrifuge at 13,000 rpm for 10 minutes at 2 - 8° C, and transfer the supernates into a clean test tube. Lysates should be used immediately or aliquoted and stored at -70 °C. Avoid repeated Phospho-Stat1 (Ser727) and pan Stat1 ELISA Kit Protocol 5 freeze-thaw cycles. Thawed lysates should be kept on ice prior to use.
For the initial experiment, we recommend to do a serial dilution testing such as 5-fold and 100-fold dilution for your cell lysates with Assay Diluent (Item E) before use.
Note: The fold dilution of sample used depends on the abundance of phosphorylated proteins and should be determined empiricallys. More of the sample can be used if signals are too weak. If signals are too strong, the sample can be diluted further.
Cell Lysate Buffer should be diluted 2-fold with deionized or distilled water before use (recommend to add protease and phosphatase inhibitors).
Assay Procedure 1. Bring all reagents to room temperature (18 - 25 °C) before use. It is recommended that all samples or Positive Control should be run at least in duplicate.
2. Add 100 µL of each sample or positive control into appropriate wells (see the following 96 well microplate formate). Cover well with plate holder and incubate for 2.5 hours at room temperature or over night at 4 °C with shaking. 96 well microplate coated with phosphorylated and pan antibodies: Phospho-Stat1 (Ser727) and pan Stat1 ELISA Kit Protocol 8 Anti-Stat1 (Ser 727) Anti-pan Stat1
3. Discard the solution and wash 4 times with 1x Wash Solution. Wash by filling each well with Wash Buffer (300 µL) using a multi-channel pipette or autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Buffer by aspirating or decanting. Invert the plate and blot it against clean paper towels.
4. Add 100 µL of prepared 1x biotinylated Stat1 antibody (Reagent Preparation step 5) to each well. Incubate for 1 hour at room temperature with shaking.
5. Discard the solution. Repeat the wash as in step3.
6. Add 100 µL of 40 fold diluted HRP-Streptavidin solution (see Reagent Preparation step 7) to each well coated with anti- Stat1 (Ser 727) on the left side (red marker, see Assay Procedure step1). Add 100 µL of 200 fold diluted HRP- 1 2 3 4 5 6 7 8 9 10 11 12 A B C D E F G H Phospho-Stat1 (Ser727) and pan Stat1 ELISA Kit Protocol 9 Streptavidin solution to each well coated with anti-pan Stat1 on the right side (black marker). Incubate for 1 hour at room temperature with shaking.
7. Discard the solution. Repeat the wash as in step3.
8. Add 100 µL of TMB One-Step Substrate Reagent (Item H) to each well. Incubate for 30 minutes at room temperature in the dark with shaking.
9. Add 50 µL of Stop Solution (Item I) to each well. Read at 450 nm immediately.
Calculation of Results ELISA data analysis: Average the duplicate readings for each sample or positive control.
