Cell Extraction Buffer is a ready-to-use lysis buffer for use in ELISA and western blotting applications for total protein extraction from mammalian cells. The buffer uses detergent-based lysis, eliminating the need for mechanical cell disruption, providing a milder and easier alternative when isolating proteins from cell cultures. The formulation helps retain the protein structure and function needed for enzyme assays or immunoassays.

Buffer formulation: 10 mM Tris, pH 7.4, 100 mM NaCl, 1 mM EDTA, 1 mM EGTA, 1 mM NaF, 20 mM Na4P2O7, 2 mM Na3VO4, 1% Triton X-100, 10% glycerol, 0.1% SDS, 0.5% deoxycholate

This cell extraction buffer does not contain protease inhibitors and should be supplemented with 1 mM PMSF and protease inhibitor cocktail just prior to use.

Frequently asked questions (FAQs)

What extraction reagents are recommended for efficient mouse tissue analysis?

We have 5 different cell and tissue extraction buffers suitable for preparing mouse cell and tissue extracts. These buffers can be used to extract cells and tissues from many other species as well. The exact compositions of all of our buffers are proprietary, but they are similar to those described by many researchers.

Four of these buffers can be used to prepare extracts which can be analyzed with our ELISA and Luminex kits and by Western blotting. Our Cell Extraction Buffer (FNN0011) contains extra phosphatase inhibitors and resembles the RIPA formulation that many people use. Our Tissue Extraction Reagents I (FNN0071) and II (FNN0081) contain different concentrations of NaCl and different surfactants, but are otherwise similar to each other. For those who prefer using an extraction buffer containing the detergent NP-40, we have our NP-40 Lysis Buffer (FNN0021). Finally, we sell a Denaturing Cell Extraction buffer (FNN0091) which contains 3 detergents and a chaotropic agent. Extracts prepared with FNN0091 can be analyzed with our ELISA kits and by Western blotting only. These buffers do not contain protease inhibitors, which the investigator should add right before use.

During my ProcartaPlex assay data analysis, I am getting a warning message that there is high bead aggregation. What should I do?

Here are possible causes and solutions for this issue:

- Check the protocol settings (make sure you select the correct DD settings).
- Check the level of sheath fluid and empty the waste.
- Before acquiring the plate, run calibration and verification beads on the Luminex instrument.

During my ProcartaPlex assay data analysis, the beads fall below or to the lower left of their bead region on the bead map. Why is this?

Here are possible causes and solutions for this issue:

This usually indicates that the beads have been photobleached. This problem can also be caused by exposing the beads to organic solvents. Unfortunately, the assay will have to be repeated because the beads cannot be restored. The beads must be protected from light and organic solvents.
Alternatively, the instrument may be off in its measurements or you may have a calibration issue. Call the manufacturer for a service appointment.

During my ProcartaPlex assay data analysis, beads do not appear in the region gated. What happened?

This indicates that an incorrect buffer was used for the final step. The Wash Solution provided in the kit must be used for washing the beads and the Reading Buffer should be used for resuspending the beads before loading them into the Luminex instrument. The osmolarity of the solution will impact the size of the bead, and any change in the bead size will alter detection by the instrument.

The bead counts for all of my ProcartaPlex assay wells are erratic. What went wrong?

Here are some suggestions:

- Before acquiring the plate, run calibration and verification beads on the Luminex instrument.
- Review the instrument settings and make sure they are appropriate for the assay being run (adjustment of needle height, make sure you select the correct bead gates and the correct DD settings).
- Shake the plate before acquisition on the instrument to resuspend the beads.
- Vortex the beads for 30 sec before adding them into the plate.
- Washing: Do not forget to keep the plate for about 2 mins on the Hand-Held Magnetic Plate Washer before emptying the plate.
