Product Summary

Cat. No.
BTE 004-09
Specificity
BTE 004-09 is specific for native human PAPP-A. Heat and SDS denatured PAPP-A is also recognized, but not acid treated PAPP-A.
Immunogen
Purified human PAPP-A
Host
Mouse
Positive Species Reactivity
Human
Negative Species Reactivity
Not determined
Isotype
IgG2b/k
Gene ID
5069
Clone Number
9
Epitope Specificity
The epitope of BTE 004-09 is different from ABS 006-01 and ABS 006-24. The epitope is located on the PAPP-A subunit of the heterotetramer.

protein A/G purified (from culture supernatant)
Form
Liquid
Solvent
0.01 M phosphate buffer, pH 7.4, containing 0.5 M NaCl and 15 mM sodium azide
Conjugation
Unconjugated BSA free
Storage
4-8ºC without exposure to light. No precautions necessary during handling.
Target
Pregnancy-associated plasma protein-A (PAPP-A, Insulin-like growth factor binding protein-4 protease, PAPP-A-proMBP complex) is a large heterotetrameric glycoprotein of approximately 500 kDa, which was first discovered in serum from pregnant women. The hetreotetramer consists of two PAPP-A subunits and two proMBP subunits. Low maternal serum levels of PAPP-A in first trimester biochemical screening is used as a marker of Down’s syndrome (trisomy 21).

Application

ELISA: In sandwich ELISA the optimal combination is BTE 004-09 used as coating antibody and biotinylated ABS 006-24 used as a detection antibody. BTE 004-09 can also be used as a detection antibody in sandwich ELISA in combination with a polyclonal antibody towards PAPP-A in coat.

WB: BTE 004-09 detect both reduced and unreduced PAPP-A in Western Blotting, though the reaction to unreduced is less than that of ABS 006-01 and ABS 006-24.

IHC-P: BTE 004-09 can be used in IHC.

IHC-F: BTE 004-09 can be used in IHC.

Staining is restricted to the syncytiotrophoblast of the chorionic villi in frozen human placenta tissue, stained with BTE 004-09.

Staining is restricted to the syncytiotrophoblast of the chorionic villi in paraffin embedded human placenta tissue, stained with BTE 004-09.
