The nucleotide-binding domain and leucine-rich repeats containing proteins (NLRs) serve as immune receptors in both plants and animals. Overaccumulation of NLRs often leads to autoimmune responses, suggesting that the levels of these immune receptors must be tightly controlled. However, the

Mitochondria from diverse organisms are capable of transporting large amounts of Ca(2+) via a ruthenium-red-sensitive, membrane-potential-dependent mechanism called the uniporter. Although the uniporter's biophysical properties have been studied extensively, its molecular composition remains elusive. We recently used comparative proteomics to

The FLAG® Expression System is a proven method to express, purify and detect recombinant fusion proteins. Sigma®, the proven provider of FLAG®, now offers a magnetic bead for immunoprecipitation, protein purification, and the study of protein-protein interactions. The ANTI-FLAG® M2 Magnetic Bead is composed of murine derived, anti-FLAG® M2 monoclonal antibody attached to superparamagnetic iron impregated 4% agarose beads, with an average diameter of 50 µm. The M2 antibody is capable of binding to fusion proteins containing a FLAG peptide sequence at the N-terminus, Met-N-terminus, or C-terminus locations in mammalian, bacterial, and plant extracts.

May I ask a question about the product? Does "1mL" mean 1 mL Slurry plus 50% glycerol, which is 2 mL in total? Same as other (e.g., 10 mL = 50% slurry with total 20 mL volume)
1 Antwort-
The "1mL" indicates that this product is supplied at a volume of 1 milliliter. This ANTI-FLAG M2 affinity gel is supplied as a 50% suspension in 50% glycerol with 10 mM sodium phosphate and 150 mM sodium chloride, pH 7.4, containing 0.02% (w/v) sodium azide (PBS/A).

Is there a generic agarose bead available for purchase that can be used as a control to test for non-specific binding, in the case that something is binding to the agarose bead itself rather than the tag? If it is not listed on the site, is there a possibility of obtaining generic agarose beads through alternative means? Alternatively, could any information be provided to determine if another provider's generic agarose beads are produced in a similar manner for this specific purpose?
1 Antwort-
Yes, there are two options available for a generic agarose bead as a control to test for non-specific binding. One option is Product Number. 4B200, Sepharose® 4B, which can be used for sample preclearing and is equivalent to the beads in the FLAG affinity product. The other option is Product Number: A0919, Mouse IgG−Agarose, which can serve as a conjugated antibody bead control.

Is there a protocol for regeneration?
1 Antwort-
Please see the link below to the product data-sheet. Instructions state that the column should be regenerated immediately after use by washing with three column volumes of 0.1 M glycine HCI, pH 3.5. The column should be immediately re-equilibrated in TBS until the effluent is at neutral pH:

I am using Product No. A2220, ANTI-FLAG® M2 Affinity Gel, and have a lot of non-specific proteins that are eluting with my FLAG®-tagged protein. How can I get rid of these?
1 Antwort-
The product bulletin for Product A2220, ANTI-FLAG® M2 affinity gel indicates:Pre-clear lysate with Mouse IgG-Agarose (Product A0919) to remove nonspecific binding proteins. Alternatively, you can use the unconjugated resin (Product 4B200) for this purpose. Other methods to remove non-specific binding from the resin would be to increase the stringency of the washes by increasing salt concentration (the resin can tolerate up to 1M NaCl) or including detergents that are compatible with the resin.

When using Product No. A2220, ANTI-FLAG® M2 Affinity Gel, I see bands at 20-25 kDa and 50-60 kDa appearing in my Westerns that are not my FLAG®-tagged protein. How can I prevent this?
1 Antwort-
As a result of the conjugation, there may be some M2 antibody that is not conjugated to the resin, but is associated with the resin and may appear in acid elutions as heavy and light chain when using the anti-mouse IgG conjugated secondary antibody. We recommend an acid wash (0.1 M glycine-HCL pH 3.5) and neutralization of the resin (do not allow the acid wash to sit on the resin longer than 20 minutes) prior to applying the lysate. Another way to avoid this is to use a directly conjugated FLAG® antibody for detection such as product A8592 ANTI-FLAG® M2 HRP, or the rabbit anti-FLAG® polyclonal antibody, F7425.

When using ANTI-FLAG M2 Affinity Gel, Product A2220, should I use a 3X FLAG peptide or a 1X FLAG peptide to elute my protein?
1 Antwort-
If you have a 3X FLAG-tagged protein, then you will need to use the 3X FLAG peptide. If you have a 1X FLAG-tagged protein, you can use the 1X FLAG peptide or the 3X FLAG peptide. We have not noticed a significant difference in elution efficiency by using a 3X FLAG peptide on a 1X FLAG-tagged protein.

How should I elute my protein when using Product No. A2220, ANTI-FLAG® M2 Affinity Gel?
1 Antwort-
Elution with the peptide is the most gentle method. Acid elution (0.1 M glycine-HCL pH 3.5) is a more stringent method of elution, and should be evaluated for its effect on your protein if it is to be used in downstream applications. Boiling the resin in sample buffer is the most denaturing condition. If this condition is used, the resin cannot be re-used, due to the presence of SDS and/or reducing agents. The elution information can be viewed on A2220 product information sheet (under Documents, above).
