General description

ANTI-FLAG® M1 Agarose Affinity Gel is a purified mouse IgG2B monoclonal antibody covalently attached to agarose.

Specificity

Binding specificity: Free N-Terminus of FLAG sequence
N-Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys-C

Application

For purification of N-terminal FLAG fusion proteins. Since binding is Ca2+-dependent, proteins can be eluted with a buffer containing EDTA, as well as by the standard methods using either FLAG peptide or glycine-HCl buffer, pH 3. ANTI-FLAG M1 does not bind to Met-FLAG fusion proteins, so this resin is not appropriate for purifying unprocessed, cytoplasmically expressed fusion proteins.

Affinity gel is for calcium mediated purification of N-terminal FLAG fusion proteins.

immunoprecipitation (IP): suitable

Elution - FLAG peptide, Glycine, pH 3.5 EDTA

FLAG® Literature portal.

Features and Benefits

  • Typically purify fusion proteins from crude lysates to single band purity in just one chromatography step.
  • Fusion protein may be eluted from affinity resin by mild elution with EDTA.
  • A solution of FLAG peptide can be used for gentle, non-denaturing elution of FLAG fusion proteins.

Physical form

Suspension of beaded agarose in 50% glycerol containing 10 mM sodium phosphate, 150 mM NaCl, pH 7.4, 0.02% (w/v) sodium azide

Other Notes

ANTI-FLAG® M1 does not bind to Met-FLAG fusion proteins, so this resin is not appropriate for purifying unprocessed, cytoplasmically expressed fusion proteins.

Certificate of Analysis
Certificate of Origin
  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Will Product A4596, ANTI-FLAG® M1 Agarose Affinity Gel, work for my C-terminal FLAG-tagged protein?

    No.  The M1 FLAG antibody resin will only bind proteins that are free N-terminal FLAG tagged proteins.  It will not recognize C-terminal FLAG tagged proteins or Met-N-terminal FLAG tagged proteins.

  4. Can I use Phosphate Buffered Saline (PBS) instead of Tris Buffered Saline (TBS) with Product A4596, ANTI-FLAG® M1 Agarose Affinity Gel?

    We do not recommend the use of phosphate buffers since calcium is required for binding.  This can result in the formation of insoluble calcium phosphates in the presence of PBS.

  5. How much calcium is required for binding of my FLAG-tagged protein to Product A4596, ANTI-FLAG® M1 Agarose Affinity Gel?

    10 mM calcium chloride is recommended for binding.

  6. What reagents are compatible with Product A4596, ANTI-FLAG® M1 Agarose Affinity Gel?

    The ANTI-FLAG M1 Affinity Gel is resistant to the following detergents: 5.0 % Tween-20; 5.0 % Triton X-100; 0.1 % NP-40; 0.1 % CHAPS and 0.2 % digitonin. It can also be used with 1.0 M NaCl or 1.0 M urea. Do not use the gel in the presence of SDS, deoxycholate or guanidine HCl.

  7. How do I find price and availability?

Phosphoribosylformylglycinamidine synthase (PFAS) is an essential enzyme in de novo synthesis of purine. Previously, PFAS has been reported to modulate RIG-I activation during viral infection via deamidation. In this study, we sought to identify potential substrates that PFAS can deamidate....

Recent studies have shown that hyperinsulinemia may increase the cancer risk. Moreover, many tumors demonstrate an increased activation of IR signaling pathways. Phosphatidylinositol 3-kinase (PI3K) is necessary for insulin action. In epithelial cells, which do not express GLUT4 and gluconeogenic...

The SU(VAR)3-9-like histone methyltransferases usually catalyze repressive histone H3K9 methylation and are involved in transcriptional gene silencing in eukaryotic organisms. We identified a putative SU(VAR)3-9-like histone methyltransferase SUVR2 by a forward genetic screen and demonstrated that it is involved in...
