Some examples of substrates used (also known as chromogens) are AEC (3-Amino-9-EthylCarbazole), or DAB (3,3'-Diaminobenzidine). Use of one of these reagents after exposure to the necessary enzyme (e.g., horseradish peroxidase conjugated to an antibody reagent) produces a positive immunoreaction product.
1. Know When You Ovulate after Childbirth. Most women experience an extended period of bleeding immediately after giving birth. The bleeding will get lighter and lighter, lasting about six weeks. It is extremely unlikely that a woman will become pregnant during this time, although it is not impossible.
If you are pregnant, you will typically not give consent until the child has been safely delivered. Most states have a waiting period, to give you time to recover from the birth and not be under the influence of pain medication. The waiting period can be as short as 12 hours or up to 15 days. The typical waiting period is 24 to 48 hours. Consent documents will be signed in front of a notary or a judge.
