

Makesurethatyoursampleslidesarecleanandsealed.UseWindexandcottonballsorKimwipestoclean

coverslips.Fixedsamplesneedtobesealedwithnailpolish.

Checktheobjectives.The10xand20xobjectivesareDRYobjectives,andshouldNEVERhaveoilonthem!

Thereare40xand63xOILimmersionobjectives,anda63xWATERimmersionobjectivealsoonthis

microscope.Ifoilimmersionobjectiveshaveoilonthem,wipethelensgentlyonlywithlenspaper.

BasicOperationofLeicaDMIRE2Microsocpe.

Bright‐fieldviewing:

1. Placeyoursampleslidewithcoverslip

(preferably#1.5thickness)facingdowntothe

objectiveonthestage.



2. Forbright‐fieldviewing,turnonthemicroscope

halogenlamplightbyturningthewheel b

towardyouandturntheVIS‐SCANswitchcto

VISposition(Note:switchbacktoScanpositionforconfocalscanning,see

below)



3. Startwithlowmagnificationobjectives(10Xor20X)firsttofocusontoyour

specimen.Youcanplacethedesiredobjectiveinpositionbyturningthe

lensturret dbyhandorbyclickingObjbutton andselectingan

objectiveyouwanttouse(recommended;seebelow).Theinformationof

theselectedobjectiveandtheirz‐positioncanbereadonthereadout

panel eatthefrontofthescope.



4. FocusontothesamplebymovingtheobjectiveturretwiththeCoarse

FocusButtonsf(upperandlower)andtheFineFocusKnob g.Pushthe

upperCoarseButtontobringtheobjectivetotheupperlimit(“0µm”)

position–wherethemicroscopehasbeencalibratedforyoursampleto

benearinfocus.



5. UsetheFinefocusknobtofinetunefocusing.Theextentofthefine

movementcanbesetfromS0(veryfine)toS3(coarse)bypressingthe

STEPbutton h(S2isrecommendedformostcases).

PleaseDONOTpresstheLEARN,CHANGE,orbuttons.



6. Withmostcellsortissuesamplesstainedwithfluorescentdye,you

couldeasilyfocustoyoursamplewithafluorescencemode(see

below)orPhaseContrastmode.ForPhaseContrastmodewith10xor

20xobjectives,turntheCondenserRingi toselectPH1(for10x)or

PH2(for20x).



7. Forusingoilorwaterimmersionlens,lowertheobjectiveturret

slightly,exposethelensbyturningtheturrethalfwaybyhand,and

placeadropofoilorwaterontheobjective(becarefulnottotouchthelensdirectlywithapplication

tools!).Placetheslideovertheobjectiveandraisetheobjectiveuntiltheoiljustspreadsoutasitcontacts

theslide.Usefindfocusknobtograduallybringyoursampleintofocus.Checkyourslideoccasionallyto

makesurethatyouarenotpushinguptheslidewiththeobjective.Thiscandamagetheobjectivelensand

yoursample!

Fluorescentviewing:

Youcancheckyoursampletoseeifyourfluorescencelabelingworksby

usingthemercurylampilluminationandtheappropriatefiltersets.The

microscopehasfiltersetsforviewingDAPI(A),greenfluorescence(I3)

andredfluorescence(N2.1).

1. Presseithertheleftorrighthorizontalarrowbutton jonthefront

ofthescopetochoosethefilter(FLUO)set.“Scan”positionhasno

filtersetinplaceandisusedforlaserconfocalscanning.The

fluorescentlightcanbeblocked(closed)oremittedbypressingthe

Shutter 1) button(The“closed”lightshouldbeoffforfluorescent

viewing.).

2. TurntheVIS‐SCANswitch 1! toScanpositiontoblockthe

transmittedbright‐fieldlight,ifnecessary.

3. Examinethesamplethroughtheeyepieces.(MakesurethatPORTSisinVISand

MAGisat1x.Ifnot,changeitselectingVisualfromMicCtrlbuttoninLCS

programwindow.)

4. Whenyouarereadytoscanyoursamplewithlaser,closetheSHUTTER1) to

preventanyunnecessarybleachingofthesamplewithmercuryarclamplight.

SequentialScanningMode

Thisconfocalmicroscopycandetectupto

fourchannels(3fluorescenceand1

transmission)simultaneouslyaslongasall

theexcitationandemissionspectraof

fluorophoresarewellseparated.Imagingof

samplesstainedwithdifferentdyesthus

simplyrequiresmanipulationoflaserpower

andadjustmentofthedetectorbandwidth.

However,oftenexcitationofone

fluorophoremaycausetheemissionto

appearintotherangeofanother(bleed‐

through)orcanbeinducedbyneighboring

laserlines(cross‐talk),bothofwhich

producefalsesignals.Toavoidthese,the

sampleshouldbescannedsequentiallyby

collectingonefluorophoresignalatany

giventime.Therearetwowaystosetup

sequentialscanmodedependingon

fluorescenceofyoursample.

Toscansequentiallythesamplewithoutneedtouse405nmUVlaser(noDAPIstaining):

1. Choosethebeamsettingparameter

foryourfluorophores(forexample,

GFPandDsRED)byselectingtheLeica

FITC‐TRITCfromthepresetlist).Itwill

setlaserlines,dichroicmirror,and

PMTsforsimultaneousimagingofthe

twocolors.



2. Setupaconditionforone

fluorophore(i.e.FITC)byonly

activatingandadjustingthelaserlevel

andthePMT(i.e.decreasethe561

thePMT2Activebox).



3. ClickSavebuttonbontheBeamPath
