MEMFA (MOPS/EGTA/Magnesium Sulfate/Formaldehyde Buffer)
| 1X | 10X | for 1 L 10X | |
|---|---|---|---|
| MOPS (pH 7.4) | 0.1 M | 1.0 M | 209.27 g |
| EGTA | 2 mM | 20 mM | 7.608 g |
| MgSO4 | 1 mM | 10 mM | 2.46 g |
| Formaldehyde | 3.7% |
- Prepare a 10 X solution without the formaldehyde for storage. Add fresh formaldehyde(1/10 volume of standard 30% stock) prior to use. The solution will turn yellow with age and when autoclaved.
Dent's Fix (Methanol/DMSO)
- 4 volumes methanol
- 1 volume DMSO
Bleaching solution (Mayor et al. 1995)
1% H202 5% formamide 0.5 X SSC(standard saline citrate)
20x PBS (phosphate-buffered saline)
- Na2PO4 H20 - 5.12 g
"Ha2HPO4 - 23.88 g
- NaCl - 204.4 g
- distilled water - 800 ml
Adjust pH to 7.4 and volume to 1 liter.
Goat Serum (GS) (Life Technologies; Mycoplasma-tested) 500 ml

PBT
- PBS (phosphate buffered saline)
- 2 mg/ml BSA (bovine serum albumin) (Fraction 5, reagent grade)
- 0.01% Triton X-100
DAB (Diaminobenzidine; Polyscience)
