Related Product Information for SP1/PSbeta1-G elisa kit
Introduction: Human pregnancy-specific beta-1 glycoproteins (SP1) are a group of closely related placental glycoproteins and members of the immunoglobulin superfamily. These proteins can be produced in human intestinal tissue, T lymphocytes and male reproductive tract. However, they are mainly synthesized in the syncytiotrophoblast of placenta and secreted into the maternal circulation in increasing amounts as gestation progresses. In males and non-pregnant females, circulating levels of the protein are less than 3 ug/ml. SP1 levels have been suggested to correlate with certain obstetrical complications.
Principle of the Assay: This assay employs the competitive inhibition enzyme immunoassay technique. An antibody specific for SP1 antibody has been pre-coated onto a microplate. A competitive inhibition reaction is launched between HRP labeled SP1 and unlabeled SP1 (Standards or samples) with the antibody specific for SP1. The substrate solutions are added to the wells, respectively. And the color develops in opposite to the amount of SP1 bound in the initial step. The color development is stopped and the intensity of the color is measured.

NCBI Description
The human placenta is a multihormonal endocrine organ that produces hormones, enzymes, and other molecules that support fetal survival and development. Pregnancy-specific beta-1-glycoprotein (PSBG, PSG) is a major product of the syncytiotrophoblast, reaching concentrations of 100 to 290 mg/l at term in the serum of pregnant women (Horne et al., 1976 [PubMed 971765]). PSG is a member of the immunoglobulin (Ig) superfamily (Watanabe and Chou, 1988 [PubMed 3257488]; Streydio et al., 1988 [PubMed 3260773]).[supplied by OMIM, Oct 2009]

Product Notes
The Human SP1/PSbeta1-G psg1 (Catalog #AAA702944) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA702944 ELISA Kit recognizes Human SP1/PSbeta1-G. It is sometimes possible for the material contained within the vial of "Pregnancy Specific beta1 Glycoprotein (SP1/PSbeta1-G), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
