Thank you for your question. We do not recommend ever freezing our primary antibodies. The antibody is vialed in a buffer than contains gelatin as a stabilizer protein, and when frozen the gelatin can sequester IgG out of solution and negatively impact antibody performance. For long term storage, we recommend storing at 4 degrees C. If you are concerned about contamination, then we would recommend aliquoting the antibody for long-term storage at 4 degrees C.
