- 抗原
- Mouse anti-GST monoclonal antibody
- Lot Number
- 1214
- Method validated
- Western Blotting
- Positive Control
- BL21 bacteria cells were transformed with an in-house GST expression vector pGST
- Negative Control
- Empty vector cell lysate
- Notes
- Based on the 12% GST content in total cell lysate of BL21-pGST (+IPTG), there is an estimated 1 ng of GST protein in 0.01 ug of total protein with IPTG induction. Therefore, the detection limit of mouse anti-GST monoclonal antibody is lower than 1 ng of GST protein.
- Primary Antibody
- Antibody: Mouse anti-GST monoclonal antibody
- Lot number: 1214
- Dilution: 1:1000
- Secondary Antibody
- Antibody: HRP labeled secondary anti-mouse antibody
- Lot number: 390630
- Dilution: 1:2000
- Full Protocol
- **I. Reagent preparation**
- 1. BL21 bacteria cells were transformed with an in-house GST expression vector pGST.
- 2. Individual colony was inoculated in 2xYT medium and cultured at 37°C with shaking for 5 hrs followed by IPTG (1mM) induction for 2 hrs. Bacteria was grown to OD600=0.6-0.8 (5 hr) when IPTG was added.
- 3. Cells were centrifuged at top speed and pellets were collected.
- 4. Cell pellets were lysed in SDS-PAGE sample buffer.
- 5. Protein concentration was assayed using DC protein assay kit (Bio-Rad).
- 6. 50 ug of cell lysate was loaded and protein was separated by SDS-PAGE.
- 7. Gel was stained with SimplyBlue Safe Stain (Invitrogen) at room temperature.
- 8. GST content in IPTG induced samples was analyzed by Quantity One software (Bio-Rad).
- **II. Western blot validation**
- 1. Cell lysates from BL21 host cells, BL21-pGST transformed cells with or without IPTG induction were loaded and proteins were separated by SDS-PAGE followed by Western transfer to a nitrocellulose membrane.
- 2. Membrane was blocked with 2% powder milk (Bio-Rad) for 1 hr at room temperature.
- 3. Membrane was incubated with mouse anti-GST monoclonal antibody (1:1000 dilution) at 4°C overnight with shaking.
- 4. Membrane was washed with TBST three times for 10 min.
- 5. After washing, membrane was incubated with HRP labeled secondary anti-mouse antibody (1:2000 dilution, GE Healthcare) with shaking at room temperature for 1 hr.
- 6. Membrane was washed with TBST three times for 10 min.
- 7. After washing, membrane was incubated with SuperSignal West Pico substrate (Thermo Scientific) for 5 min at room temperature.
- 8. Membrane was analyzed by ChemiDoc XRS gel documentation system (Bio-Rad).

Based on the 12% GST content in total cell lysate of BL21-pGST (+IPTG), there is an

the detection limit of mouse anti-GST monoclonal antibody is lower than 1 ng of GST
