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.
As the pregnancy progresses, the survival rate continually improves, with the rate of complications gradually falling. By the end of 27 weeks, the survival rate nears 90%. Survival, however, is not enough to consider it a âsafeâ time to give birth. A majority of babies born after 32 weeks of pregnancy will not have lasting difficulties. By 37 weeks, most babies will be released from the hospital just like full-term babies, requiring no extra care. This is the time at which I would consider it safe to give birth.
