The Sheep PL (Placental Lactogen) ELISA Kit is specifically designed for the accurate measurement of placental lactogen levels in sheep samples. With its high sensitivity and specificity, this kit ensures reliable and reproducible results, making it a valuable tool for researchers studying placental lactogen's role in pregnancy and fetal development. Placental lactogen is a key hormone produced by the placenta during pregnancy, playing a crucial role in regulating maternal metabolism, fetal growth, and lactation.
Abnormal levels of placental lactogen have been associated with various reproductive disorders and complications, making it a vital biomarker for investigating pregnancy-related conditions and potential therapeutic interventions. Trust in the Sheep PL ELISA Kit to deliver precise and reliable results for your research needs, providing valuable insights into the intricate mechanisms of placental function and development in sheep models.

Note: The below protocol is a sample protocol. Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.
Step
Procedure
1
Reagent & Plate Preparation: Equilibrate TMB substrate for 30 minutes at room temperature. Prepare standards, samples (minimum 1:2 dilution), blanks, assign wells, and pre-wash the plate twice.
2
Sample & Biotin-Antibody Binding: Add 50 µL standard or sample followed by 50 µL biotin-labeled antibody to each well. Mix gently and incubate at 37°C for 45 minutes.
3
Washing: Wash the plate 5 times with wash buffer, allowing 1 minute soak time per wash.
4
Color Development: Add TMB substrate and incubate in the dark at 37°C for 10-20 minutes until color develops.
5
Stop Reaction: Add stop solution to terminate the reaction. The color changes from blue to yellow immediately.
6
Reading: Measure absorbance at 450 nm using a microplate reader.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant and store appropriately.
Plasma
Collect using EDTA anticoagulant, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Cell Culture Supernatant
Centrifuge at 1000 × g for 20 minutes at 4°C and collect clarified supernatant.
Cell Lysate
Lyse cells using recommended lysis buffer with protease inhibitors, centrifuge at 10,000 rpm for 10 minutes, and collect protein supernatant.
Tissue Homogenate
Homogenize tissue in PBS with protease inhibitors, centrifuge at 5000 × g for 5 minutes, and collect supernatant.
Other Sample Types
Centrifuge samples at 1000 × g for 15 minutes at 2–8°C and collect supernatant. For additional guidance, please contact techsupport@assaygenie.com.
