- GnRH Analogs
- Hypothalamic-pituitary axis
- ART protocols, ovulation induction models, hypogonadism studies
- Receptor agonism (short-term stimulation) or desensitization (long-term suppression)
- Require precise sequencing at positions 6 and 10. Single substitutions eliminate receptor selectivity
- Kisspeptin Variants
- GnRH neuron activation
- Pulsatile gonadotropin secretion, hypothalamic amenorrhea models
- GPR54 receptor agonism, frequency-dependent LH/FSH ratio
- Degrades rapidly in plasma (half-life <3 min). Requires protease-resistant analogs for in vivo work
- Inhibin/Activin
- FSH regulation
- PCOS models, ovarian reserve studies, granulosa cell culture
- TGF-β receptor binding, Smad2/3 signaling
- Must verify glycosylation state. Unglycosylated forms show 10-fold reduced bioactivity
- AMH/GDF9/BMP15
- Oocyte-granulosa signaling
- IVM protocols, folliculogenesis studies
- Paracrine growth factor, cumulus expansion
- Requires specific disulfide bond patterns. Reducing conditions abolish activity
- LIF/IL-11
- Endometrial decidualization
- Implantation models, thin endometrium studies
- STAT3/JAK pathway activation
- Temperature-sensitive. Activity drops 40% after 24 hours at room temperature
- HB-EGF
- Blastocyst adhesion
- Embryo selection, implantation competence assays
- ErbB4 receptor binding, trophectoderm attachment
- Fluorescent labeling must preserve ectodomain structure or binding affinity is lost
