Rabbit polyclonal antibody to Presenilin 1 (1-20): IgG

$297.00USD


Catalogue No. R-1605-500
Description Presenilin-1 (PSEN1) is a multi-pass membrane protein and component of the gamma-secretase complex. PSEN1 is thought to play a role in intracellular signaling and gene expression or in linking chromatin to the nuclear membrane. It may also play a role in hematopoiesis. Defects in PSEN1 are a cause of Alzheimer disease type 3 (AD3), a familial early-onset form of Alzheimer disease (Ref:SWISS-Prot).
Batch No. See product label
Unit size 500 µg
Antigen A synthetic peptide corresponding to a region (1-20 aa) from the N-terminus of human Presenilin 1 conjugated to Diptheria toxoid.
Sequence MTELPAPLSYFQNAQMSEDN-C
Antibody Type Polyclonal
Other Names Presenilin 1; PS-1; Protein S182; PS1-CTF12; PSEN1; AD3; PS1; PSNL1;
Accession P49768 PSN1_HUMAN;
Produced in Rabbit
Applications IF and WB. Suggested dilution of 1:2,000 is recommended for WB. On SDS-PAGE, the predominant form detected by this antibody is the N-terminal Presenilin 1 fragment of approx 29 kDa. The uncleaved form of Presenilin 1 migrates to approx 45 kDa. Human and mouse brain samples commonly prepared with reducing agent (50mM DTT), urea (2.3M), SDS (1%) in 62.5 mM Tris-HCl pH 6.8 sample buffer heated to 50C for 15 min. The suggested dilution for IF is 1:100 for acetone or paraformaldehyde fixed cells or tissue. Biosensis recommends that the optimal working dilution should be determined by the end user.
Specificity Specificity confirmed by WB and IF using transfected cells, Presenilin 1 knock-out mouse cells, mouse and human brain.
Species Against Human; mouse; rat; guinea pig. Expected to cross-react with other species due to sequence homology.
