ER Special Dyes

Dear Colleaguses,

I am going to localize a protein which is from soybean.Bioinformatic
analysis indicates it is maybe licalized in ER membrane.Initially I
would likt to fuse my protein to GFP and check its
localization.Alternatively I can employe antibody against my protein to
verify its localization. Certainly the later technique is
time-consuming. Would you kindly give me your suggestions related to
special marker dyes for ER or ER-special marker proteins? In addtion I
know some special dyes and antibody for ER-special marker proteins are
commercially availabe. I look foward to comments or ideas of experts to
guide me to select better dyes or marker protein Ab? Many thanks in advance.

Best regards.

Jinxiang

I have it on good authority from a labmate that sucrose-gradients are
a great way to check for protein localisation. I gather it involves a
long centrifuge cycle but yields very reliable results.

check Molecular Probes (Invitrogen.com) for ER-specicic life-cell markers.
Alternatively of course you can use an fluorescent antibody against an
ER-specific protein, however, then the cell has to be permeabilised.
