CD45 etal in rabbit spleen
|From:||Kristin Gebhard Mitchell |
A collegue brought me this dilemma and I'll pass it along to ya'll...
She has frozen (not well) rabbit spleen that was post fixed in Formalin.
She used CD45 (don't know the clone) and Ki67 and some kind of
macrophage ab (not CD68) as her primary abys (seperatly), the Vector
ABC-HP kit and used AEC as her substrate. There was no pretreatment and
no counter stain.
The CD45 has high background but the no primary control was completly
clear. The others stained well...but the staining pattern is confusing.
The actual problem is that she's not certain of what it is SUPPOSED to
look like :-)
They were expecting clusters of positive cells (specific to the white
pulp?) instead they got CD45 ALL OVER, Ki67 randomly and I never saw the
macrophage but I have the impression it was all over.
I've searched thru the suggested IHC and staining links and various
search engine for examples of spleen IHC, specific for these abys or for
CD3 or some other lymphocyte marker to see what a normal pattern would
be, but no luck. And the various histology books around here don't have
a large selection of spleen material, let alone IHC on spleen.
Any ideas? Any ideas on what to search for? Any help is appreciated!
