Unit:One unit of antibodies contains 50 or 100 ul diluted-antisera in PBS or 5% glycerol containing 0.05% Na-azide. For immunohistochemistry, further dilution of 1:1,000 or 1:2,000 is recommended. Further dilution may be necessary depending on species and tissues. For instance, tyrosine hydroxylase in the rat brain can be detected with 1:2000 or more dilutions. Paraffin section requires 1:200 or more dilution. Recommended dilutions for each antibody are specified in each product specification below.
Storage:Our antisera contain a preservative, so it is stable at 4o C for several months. Alternatively, the antisera can be frozen at -80o C for at least one year. Longer storage, even at -80o C, will lead to a gradual loss of antibody titer. Avoid freezing small volumes using a “no frost” freezer. Once the antisera are diluted to 1:1000, use it within one or two days and keep it always at below 4o C but do not freeze. Do not store diluted antisera for longer than two days.
Expiration Date:One year
