ANTIBODY PURIFICATION by affinity chromatography. By Beth, Mullins Lab UCSF. To affinity purify antibodies, generate lots of E. coli lysate that contains your antigen. If the protein can stand freeze thawing, then go ahead and purify the protein from e. coli lysate and keep it frozen until you need to couple it to a CH-sepharose column. - [Read ANTIBODY PURIFICATION by affinity chromatography]

Category: Stem Cell Protocols

This protocol describes a method for freezing and thawing ES cells using cryovials. It is important to freeze ES cell stocks as soon as possible to reduce the time that they are in culture. A careful record should be kept of the number of times cells are passaged and the location of the cryovials. - [Read Freezing and Thawing of Embryonic Stem (ES) Cells Using Cryovials Protocol]

Following propagation to 1 X 108 cells, lymphoblastoid cells are conveniently stored at -80 degrees C to preserve the high molecular weight DNA in the cells until the DNA is purified. This procedure describes the steps required to harvest and freeze the c - [Read Method: Preparation of Lymphocyte Cell Pellet for Storage]

In general, peptide solutions are stable for up to a week at 4°C. However, if the peptide sequence has inherent instability (Peptide Stability), it might be better to freeze the solution when not in use. Peptide solutions at pH>8 should also be frozen when not in use. Sigma Aldrich. - [Read Peptide Handling and Storage]

Protocol describes a method for transforming Agrobacterium with plasmid DNA using a freeze-thaw technique. Although the transformation efficiency for Agrobacterium is lower than that for Escherichia coli, it is possible to obtain adequate numbers of transformants with this technique. - [Read Transformation of Agrobacterium Using the Freeze-Thaw Method Protocol]
