General description
M2 anti-FLAG purificado en gel de afinidad, es un anticuerpo monoclonal que está covalentemente unido a la agarosa. El anticuerpo se une a FLAG en los extremos N-terminal, Met-N-terminal, C-terminal y ubicaciones internas de las proteínas de fusión. La unión no es dependiente del calcio.
Elución - Péptido FLAG®, glicina, pH 3,5, 3x péptido FLAG®

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 respuesta-
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 respuesta-
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 respuesta-
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:

Is my lysis buffer compatible with Product No. A2220, ANTI-FLAG® M2 Affinity Gel?
1 respuesta-
The A2220 product information sheet (under Documents, above) contains a reagent compatibility table located on page 6. We do not recommend addition of SDS or reducing agents such as DTT, DTE or 2-mercaptoethanol to the resin. If you have a detergent listed in the table in a higher than recommended concentration, we recommend trying to dilute the sample before applying to the resin.

How should I elute my protein when using Product No. A2220, ANTI-FLAG® M2 Affinity Gel?
1 respuesta-
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).

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 respuesta-
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.

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 respuesta-
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.
