Frequently Asked Questions

What are the typical dilutions for your Tyrosine Hydroxylase antibodies, such as western blot, ELISA, formalin-fixed paraffin embedded tissue, etc.

A typical starting dilution for antibodies in immunoassays is 1:1000. Consider adjusting the dilution depending on your experimental conditions, to increase or decrease the signal-to-noise ratio, etc.

Should I store antibodies at -20 C or at -80 C? Should I aliquot them upon delivery?

Either - 20 C or - 80 C is acceptable depending on the usage, however, avoid multiple freeze-thaw cycles. Our antibodies contain glycerol which will inhibit freezing at -20 C, however, the materials will freeze at -80 C. If the antibody will be consumed within a few weeks of delivery, we recommend storage at -20 C. For long term storage, we recommend subaliquoting in single-use aliquots then storing at -80 C.
