Human Pregnancy-specific beta-1-glycoprotein 1/PSG1 ELISA Kit
The Human Pregnancy-Specific Beta-1-Glycoprotein 1 (PSG1) ELISA Kit is specifically designed for the quantitative measurement of PSG1 levels in human serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit delivers accurate and reliable results, making it an essential tool for researchers studying pregnancy-related conditions. PSG1 is a unique glycoprotein that is expressed exclusively during pregnancy, playing a critical role in immune tolerance and fetal development.
This biomarker is also associated with certain pregnancy complications and disorders, making it a valuable target for diagnostic and therapeutic interventions. Gain valuable insights into pregnancy-specific biology and pathophysiology with the Human PSG1 ELISA Kit, empowering your research with precise and dependable measurements of PSG1 levels. Elevate your studies and advance the understanding of pregnancy-related health issues with this advanced ELISA kit.

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 reagents and TMB substrate to room temperature. Set standard, test sample and control (zero) wells on the pre-coated plate and record their positions.
2
Primary Incubation: Prepare standards, samples, blanks and load into designated wells. Incubate plate at 37°C for 90 minutes to allow antigen binding.
3
Detection Antibody Binding: Add biotin-labeled detection antibody and incubate at 37°C for 60 minutes.
4
HRP-Streptavidin Binding: Add HRP-Streptavidin (SABC) and incubate at 37°C for 30 minutes.
5
Color Development: Add TMB substrate and incubate in the dark for 10–20 minutes.
6
Stop Reaction & Reading: Add stop solution and measure absorbance at 450 nm immediately.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant supernatant and store appropriately.
Plasma
Collect using anticoagulant tubes, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Tissue Homogenate
