Related introduction:


Protein A Protein G Sepharose FF is an affinity separation medium formed by bonding recombinant Protein A Protein G fusion protein (r-PAG, NRPA14S) to Sepharose microspheres. Compared with separate protein A or protein G separation medium, it has a wider binding range and can bind to all human IgG subtypes, IgA, IgE, IgM, but cannot bind to mouse IgA, IgM and serum albumin , Suitable for the extraction and detection of mouse IgG monoclonal antibodies. At the same time, the fusion of r-PAG reduces the dependence on pH, allowing binding at pH 5 ~ 8.

Application examples:


Binding buffer: 20 mM phosphate buffer, 150 mM NaCl, pH 7.4


Elution buffer: 0.1 M Glycine-HCl buffer, pH 2.5


Neutralization buffer: 1 M Tris-HCl, pH 9.0


1) 1 ml Protein A Protein G Sepharose FF pre-packed column is washed with 5-10 bed volumes of distilled water to remove the preservation solution;


2) Equilibrate 5-10 bed volumes with binding buffer and buffer;


3) Dilute 3 ml of rabbit polyantiserum to 15 ml with binding buffer, filter the sample with 0.45 μm filter;


4) Wash with binding buffer for another 5-10 bed volumes;


5) Elute the antibody with elution buffer, collect the elution peak, and adjust its pH to neutral with neutralization buffer;


6) After the target antibody is eluted, wash 5-10 column volume equilibration columns with binding buffer;


7) Analyze the eluted rabbit polyclonal antibody.

Precautions:


1) The pre-packed column is simple and convenient to use, and the purification task can be completed without equipment;


2) After the sample is eluted, the pH is generally very low, and the collected antibody solution should be neutralized to neutral with an alkaline neutralization buffer (such as 1 M Tris-HCl, pH 9.0) immediately, or pre-filled in a collection container 5% ~ 10%, pH 7.5 buffer (such as 1 M Tris-HCl or 1 M phosphate buffer) to help maintain the biological activity of the antibody and avoid antibody inactivation;


3) When using, ensure that the temperature of the column and the buffer are the same to avoid bubbles in the column bed. If bubbles have already occurred, you can repack the column by yourself;


4) After repeated use, there will be precipitated proteins, strong hydrophobic proteins, lipoproteins, liposomes and other non-specific adsorption gels, which can be cleaned with a 0.1% detergent for a short time, such as 0.1% Triton X-100 2 Column volume, immediately wash 5-10 column volumes with binding buffer. It can also be cleaned with 70% ethanol for the same cleaning.
