Kanamycin kev ua haujlwm ruaj khov ntawm ph 7.3 thiab 72 degrees C. Lub neej ib nrab (t1/2) ntawm pH 7.3 thiab 72 ° C nyob ntawm 3.3 h (k=7.26 hnub-1, qhov twg k [degradation tas li]=1 / t1 / 2) rau ampicillin kom tsis txhob muaj qhov poob ntawm kev ua haujlwm rau kanamycin, neomycin, thiab lwm yam tshuaj tua kab mob.
Kanamycin puas phem?
Peb qhov kev paub dhau los ntawm kev ua tau zoo ntawm kanamycin daim hlau yog: yog daim ntawv khaws cia kom raug siv tau li 8-10 hnub, tom qab ntawd cov phiaj pib poob lawv txoj haujlwm. Tom qab inoculation ib tug yuav tsum tsis txhob tos ntev tshaj 48 teev rau xaiv los yog Kan-R colonies.
kanamycin ruaj khov ntawm chav tsev ntev npaum li cas?
Storage/Stability
Sterile solutions can be ready by sterile filtration through a 0.2 µm filter. Kev daws tau ruaj khov ntawm 37 ° C rau kwv yees li 5 hnub.
Kanamycin puas ruaj khov ntawm chav sov?
Shipping thiab Cia: Kanamycin Sulfate yog xa tawm ntawm chav tsev kub. Rau kev ruaj ntseg siab tshaj plaws thiab siv tau ntev, khaws cia ntawm chav tsev kub thaum tau txais. Tiv thaiv los ntawm noo noo. Cov tshuaj tua kab mob feem ntau yog ntxiv rau cov xov xwm tshiab autoclaved (tom qab lawv tau txias txog li 50 ° C).
Koj khaws kanamycin li cas?
Kanamycin yog lub teeb rhiab heev. Khaws kaw kom nruj rau hauv cov thawv uas tiv taus lub teeb. "Cov kev daws teeb meem ruaj khov ntawm 37 ° C rau kwv yees li 5 hnub. Aqueous stock solutions can be stored at 2-8 °C forntev cia", Sigma.

Thaum kub taub hau hypothalamic tus ntsuas kub tau rov pib ncaj qha los ntawm?
Thaum cov kab mob raug rhuav tshem los ntawm phagocytic leukocytes, cov tshuaj hu ua endogenous pyrogens raug tso rau hauv cov ntshav. Cov pyrogens ncig mus rau hypothalamus thiab rov pib dua lub ntsuas sov. Qhov no tso cai rau lub cev qhov kub thiab txias hauv qhov uas feem ntau hu ua kub taub hau.
Ntawm qhov ntsuas kub ntawm qhov ntsuas kub emf yuav yog?
Thermo emf nce mus rau qhov siab tshaj plaws ntawm qhov kub thiab txias (θ ) hu ua nruab nrab kub thiab maj mam txo thiab nws thiaj li ua zero ntawm qhov kub (θ 1) hu ua inversion temperature. Tshaj li qhov kub ntawm inversion, Thermo emf hloov kos npe thiab tom qab ntawd nce.
Vim li cas qhov kub hnyiab ntawm qhov chaw muaj kev phom sij?
Circumferential tag nrho-thickness kub hnyiab nrog qhov ua rau poob ntawm daim tawv nqaij elasticity tuaj yeem tsim cov nyhuv tourniquet ntawm nqua thiab pob tw, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm qhov chaw perfusion, kev ua pa ntawm txoj hlab pas, thiab ua pa tsis zoo.
Thaum qhov kev sim xeb vim li cas qhov kub ntawm cov tshuaj tiv thaiv nce?
Feem ntau, qhov kub lossis siab nce ncaj qha ua rau tus nqi corrosion ntau dua vim tias cov tshuaj electrochemical feem ntau tshwm sim sai dua ntawm qhov kub siab dua. Kub nce ntxiv zog rau cov tshuaj tiv thaiv, uas ua rau nce tus nqi corrosion.
Vim li cas qhov tseem ceeb ntawm qhov muaj zog thiab qhov tsis muaj zog yog qhov tseem ceeb?
Nws yog ib qho tseem ceeb rau qhov tseem ceeb ntawm qhov ua tau zoo thiab qhov tsis muaj zog vim qhov no pab lub tuam txhab txiav txim siab txog thaj chaw uas lawv yuav tsum tau txhim kho ntxiv rau thaj chaw uas lawv ua tau zoo hauv. Vim li cas lub zog thiab qhov tsis muaj zog tseem ceeb?
