40-De­oxy-40(S)-iodo­rapamycin

The title compound, C(51)H(78)INO(12), contains a 29-membered ring incorporating amide, lactone and ester groups. It contains a total of 15 stereogenic centres. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming C(8) chains propagating in [100]. A weak intra-molecular O-H⋯O inter-action also occurs.

I-40: Implantation Failure

Background: The process of implantation involves the interaction of the human embryo and the uterine epithelium. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Management of repeated implantation failure despite transfer of good-quality embryos still rema...

Instantly switch recording modes by using the membrane potential as the trigger. Preset a voltage threshold in current-clamp mode, and MultiClamp 700B automatically switches to voltage-clamp when the membrane potential reaches that voltage level. User-specified delay allows you to perform creative new experiments. Suppress Oscillations Sudden changes in membrane or pipette parameters may result...
