Background of Dihydrofolate Reductase/DHFR

Dihydrofolate reductase, or DHFR, is an enzyme that reduces dihydrofolic acid to tetrahydrofolic acid, using NADPH as electron donor, which can be converted to the kinds of tetrahydrofolate cofactors used in 1-carbon transfer chemistry. In humans, the DHFR enzyme is encoded by the DHFR gene. It is found in the q11→q22 region of chromosome 5. What's more, DHFR belongs to the dihydrofolate reductase family, and it converts dihydrofolate into tetrahydrofolate, a methyl group shuttle required for the de novo synthesis of purines, thymidylic acid, and certain amino acids. DHFR is the key enzyme in folate metabolism. In addition, DHFR catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.

Antibody Validation

Question

Does PB9175 anti-Dihydrofolate reductase (DHFR) antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Verified customer

Asked: 2020-05-05

Answer

It shows on the product datasheet, PB9175 anti-Dihydrofolate reductase (DHFR) antibody as been tested on IHC. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

Question

Can you help my question with product PB9175, anti-Dihydrofolate reductase (DHFR) antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?

Verified Customer

Verified customer

Asked: 2020-04-21

Answer

We do not advise storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free PB9175 anti-Dihydrofolate reductase (DHFR) antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.
