Purification, IP
Each lot of this antibody is quality control tested by immunoprecipitation.
The optimal buffers and matrix concentration should be determined for each specific assay condition.
Binding: Tagged protein will bind to matrix in common physiologic buffers with pH in the range of 6.0-7.5, salt from 50-500 mM and in the presence of reasonable levels of detergent. Excess reducing agent should be avoided as the disulfide bridges holding antibody heavy and light chains may be compromised. BioLegend tests Affinity Matrix using an equilibration/binding buffer containing:
? 100 mM Tris-HCl (pH 7.5)
? 150 mM NaCl
? 0.1% Tween 20
? 0.5% BSA
? 1 mM beta-mercaptoethanol
Washing: After binding, washes with several bead volumes of buffer are recommended. Such buffer may contain increased salt, altered pH, etc. as determined empirically to remove un-tagged proteins.
Elution: Several options are available for elution.
1. SDS gel loading buffer may be applied directly to the beads in order to display all bound protein on a polyacrylamide gel/western. Note that gel loading buffer containing reducing agent will also release some antibody heavy and light chains (approx 25 and 50kD, respectively).
2. Competitive elution with epitope peptide. For epitope tag affinity matrices, prepare an elution buffer with epitope tag peptide at 400 ug/mL in 50 mM Tris-HCl (pH 7.5), 50 mM NaCl, 1 mM EDTA (pH 8.0).
3. Chemical Elution. Elution by pH or chaotropic salts is also possible. For elution by pH, either 0.1 M glycine pH 2.8 or 40 mM diethyl-amine pH 11.0 may be used.
This affinity matrix can be used for immunopurification of AU5 tagged fusion proteins from crude starting material. On an analytical scale, it can also be used for immunoprecipitating AU5 tagged proteins.

Monoclonal mouse antibody AU5 recognizes the peptide epitope, TDFYLK. This antibody was purified using protein-G chromatography, and was subsequently immobilized onto a Sepharose? fast flow matrix.
