Ki-67 is a nuclear, non-histone protein that is expressed only during active phases of the cell cycle (G1, S, G2 and M), but not in the resting phases (G0 and G1 early phase). Although the antigen has also been associated with ribosomal RNA transcription, it is strongly linked to cell proliferation and has thus been indicated as an effective marker in grading the proliferation rate of tumors, including those of the brain, breast, cervix, and prostate.
Description
Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Laemmli Tris-HCl gels.
Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) concentrations of polyacrylamide in 12-and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.
Key Features

For enriching bile-tolerant Gram-negative bacteria in the microbiological examination of pharmaceutical products.
Pancreatic digest of gelatin provide protein, vitamins and amino acids; glucose carbon source; disodium hydrogen phosphate and potassium dihydrogen phosphate as a buffer; ox bile and brilliant green as selective antibacterial agent, inhibiting the growth of non-Enterobacteriaceae.
| Ingredients | /liter |
| Pancreatic digest of gelatin | 10g |
| Glucose monohydrate | 5g |
| Dehydrated ox bile | 20g |
| Potassium dihydrogen phosphate | 2g |
| Disodium hydrogen phosphate dihydrate | 8g |
| Brilliant green | 15mg |
| pH7.2±0.2 at 25°C | |
Suspend 45g in 1L of distilled water,stir until completely dissolved and dispense 100 mL into test tubes , heat at 100 °C for 30 min in a waterbath or flowing steam.
The following quality control strains were inoculated and cultured at 30-35℃ for 24h-48h. The results are as follows:
| Quality control strains | Inoculum (CFU) | Growth |
| Escherichia coli ATCC8739 | < 100 | Good growth |
| Pseudomonas aeruginosa ATCC9027 | ||
| Staphylococcus aureus ATCC6538 | > 100 | Inhibited |
2-30℃，Keep container tightly closed, avoid direct sunlight.
Use before expiry date on the label.
1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort
2. Keep container tightly closed after using to prevent clumping.
Microbiological contamination was disposed by autoclaving at 121°C for
30 minutes.
Intended Use For enriching bile-tolerant Gram-negative bacteria in the microbiological examination of pharmaceutical products. Principle and Interpretation Pancreatic digest of gelatin pro……
