ANTIBODIES FOR NEUROLOGICAL DISEASE RESEARCH:
PRESENILINS AND NICASTRIN
Use the antibodies that your colleagues are using: Biosensis has a number of highly published antibodies for your research into neurological diseases. In this newsletter we are highlighting three of our most popular Presenilin and Nicastrin antibodies.
There are many more great products for the study of Alzheimer's and Parkinson's disease. Check them out here.
Rabbit Polyclonal Presenilin 1 Antibody Rabbit Polyclonal Presenilin 2 Loop Region
Figure 1. Immunofluorescence analysis of Presenilin 1 with IgG-purified rabbit antibody raised against the N-terminal region (1-20) of PS1 protein (Cat# R-1605-500). PS1-positive and knock-out neurosphere-derived cells after differentiation were fixed with paraformaldehyde (15 min) and stained with R-1605-500 (20μg/ml). An antibody against the loop region of Presenilin 1 (Cat# R-1680-500) is also available.
Figure 2.
Western immunoblotting of mouse and human Presenilin 2 protein in mouse cell line extracts, various mouse tissues and a human cell line with rabbit anti-Presenilin 2 antibody (Cat# R-1681-500). Membrane proteins were prepared and loaded as 20 µg protein per lane. Whole serum anti-PS2 loop antibody was used at 1:1000 dilution. CTF: C-terminal fragment.

NICASTRIN:

Rabbit Polyclonal Nicastrin C-Terminal (691-709) and Central Region (334-346) Antibodies
Figure: Western immunoblotting analysis of mouse Nicastrin protein in PS1-deficient cell line and adult mouse brain with Nicastrin central region antibody (Cat# R-1685-500, right panel) and C-terminal Nicastrin antibody (Cat# R-1684-500, left panel). Membrane proteins were prepared and loaded as 20 µg protein per lane.
