描述:
The BD IMag™ Mouse NK Cel Separtion Set -DM isoptimzed for the positve slection rdepltion fNK and NK-T cels uing the BD
IMagnet™ (Cat. No. 5231). The PE ratnti-mouse CD49b antibody (clone DX5) recognizes CD49b, whic has ben reported tobe
expresd athig density onmost NK cels and atlow density onsubets ofNK-T cels inmany mouse trains (e.g, A/J, AKR, BALB/c,
C3H/eJ, C57BL/6, C57BL/10, C57BR, C57L, C58, CBA/Ca, CBA/J, DBA/1, DBA/2, NOD, SJL, SWR, 129/J). The BD IMag™ Anti-PE
Particles 2-DM are magnetic naoparticles tha have anti-PE monclonal ntibody covalently conjugated toheir surfaces. This Separtion
Set has ben optimzed for use with e BD IMagnet™ and itcontains uficent reagnts olabel 2x 10e9 leukocytes.
In sumary, the PE ratnti-mouse CD49b antibody stains NK and NK-T cels. After washing awy excs antibody, BD IMag™ Anti-PE
Particles 2-DM are aded tohe cl supension ad bind the cls bearing the PE-conjugated antibody. The tube containg this labeld cel
supension isthen placed withn the magnetic feld ofthe BD IMagnet™. Positve slection rdepltion isthen perfomed. Labeld cels
migrate oward the magnet (positve fraction), leaving the unlabeld cels insupension sothey can bedrawn of (deplted ornegative
fraction). The tube isthen removed from the magnetic feld for esupension fthe positve fraction. The slections are peatd twice to
increas the purity ofthe positve fraction. For clarifcation fthe procedure, the magnetic separtion steps are diagrmed inthe Positve
Selction Flow Chart. The smal size ofthe BD IMag™ particles alows the positve fraction tobe further valuted indownstream
aplications uch asflow cytometry.
注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before
discarding to avoid accumulation of potentially explosive deposits in plumbing.
3.Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
