Kodi Centrifuge Imatha Kulekanitsa Mchere ndi Madzi?

Chiyambi:

Kutsegula payipi ndi njira yomwe imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, kuyambira kafukufuku wasayansi mpaka ntchito zamafakitale. Funso limodzi lomwe limabuka nthawi zambiri ndilakuti ngati chotsegula payipi chingathe kulekanitsa mchere ndi madzi moyenera. M'nkhaniyi, tifufuza za sayansi ya kutsegulira payipi ndikuwona momwe ingagwiritsidwire ntchito kulekanitsa mchere ndi madzi. Kuyambira kumvetsetsa mfundo za njira iyi mpaka kuwunika zofooka zake, cholinga chathu ndikupereka chithunzithunzi chokwanira.

Sayansi Yokhudza Kuzungulira kwa Maginito:

1. Mfundo ya Mphamvu ya Pakati

Chisakanizo chikayikidwa mu centrifuge, chimayikidwa ndi mphamvu ya centrifugal. Mphamvu imeneyi imapangitsa kuti zigawo zokhuthala zisunthe kupita kukhoma lakunja la chubu cha centrifuge, ndikupanga pellet, pomwe zigawo zokhuthala pang'ono, monga zamadzimadzi, zimakhala pafupi ndi pakati.

2. Kulekanitsa Mchere ndi Madzi

Mchere umasungunuka mosavuta m'madzi, ndikupanga ma ayoni omwe amagawidwa mofanana mumadzimadzi onse. Chifukwa ma ayoni amchere amafalikira ndipo sasonkhana kwambiri, sakhudzidwa ndi mphamvu ya centrifugal. Chifukwa chake, kungogwiritsa ntchito centrifuge kuzunguliza chisakanizo cha mchere ndi madzi sikungapangitse kuti zilekanitsidwe.

Udindo wa Density-Gradient Centrifugation:

Pofuna kulekanitsa mchere ndi madzi pogwiritsa ntchito centrifuge, njira ina yotchedwa density-gradient centrifugation ingagwiritsidwe ntchito. Njira imeneyi imadalira kupanga density gradient mkati mwa chubu cha centrifuge.

3. Kupanga Kachulukidwe ka Gradient

Kuchuluka kwa kachulukidwe ka madzi kungapangidwe powonjezera zinthu monga sucrose kapena cesium chloride ku yankho. Pamene yankho likuyikidwa mu centrifuge, zinthuzo zimapanga kuchuluka komwe kachulukidwe ka madzi kamawonjezeka kapena kuchepa pang'onopang'ono m'litali mwa chubu.

4. Njira Yopatukana

Pamene chisakanizocho chikuyikidwa mu chubu chozungulira, tinthu ta mchere tochuluka timasunthira kudera lomwe lili ndi kuchuluka kwakukulu, pomwe mamolekyu amadzi amakhala pafupi ndi pakati. Izi zimathandiza kuti mchere ukhale wosiyana pang'ono ndi madzi.

Zofooka za Centrifugation:

5. Kuchita Bwino ndi Kuyera

Ngakhale kuti kugawa mchere m'madzi ndi kuchuluka kwa ma gradient kungathandize kulekanitsa mchere ndi madzi, ndikofunikira kudziwa kuti kulekanitsa kwathunthu sikungatheke nthawi zonse. Mchere wina ukhoza kukhalabe mu gawo la madzi, zomwe zimapangitsa kuti pakhale yankho lomwe silinayeretsedwe mokwanira.

6. Zonyansa Zina

Kugawa zinthu m'magawo apakati (centrifugation) kumathandiza kwambiri kulekanitsa zinthu kutengera kuchuluka kwake. Komabe, sikuchotsa zinthu zina zodetsa, monga mpweya wosungunuka, mankhwala achilengedwe, kapena tinthu tomwe timakhala mu chisakanizo cha madzi ndi mchere.

7. Zofunikira pa Mphamvu

Kuyendetsa magetsi pogwiritsa ntchito centrifugation ndi njira yogwiritsa ntchito mphamvu zambiri. Kuti pakhale kulekanitsa kogwira mtima, pamafunika nthawi yayitali yozungulira mwachangu, zomwe zingawonjezere kugwiritsa ntchito mphamvu yonse pa ntchitoyi.

Kugwiritsa Ntchito Centrifugation:

8. Ntchito Zamakampani

Kutsegula mpweya pogwiritsa ntchito centrifugation kumagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo mankhwala, sayansi ya zamoyo, ndi kukonza chakudya. Nthawi zambiri amagwiritsidwa ntchito polekanitsa zinthu zolimba ndi zamadzimadzi, komanso poyeretsa ndi kuyika zinthu zosiyanasiyana m'thupi.

9. Kafukufuku wa Zamoyo za Mamolekyulu

Mu kafukufuku wa zamoyo zamamolekyu, kugawa kwa maselo m'maselo kumachita gawo lofunika kwambiri pakuyeretsa DNA, RNA, ndi mapuloteni. Njira imeneyi imathandiza asayansi kuphunzira ndikusintha mamolekyu amenewa kuti agwiritsidwe ntchito m'njira zosiyanasiyana, kuphatikizapo ukadaulo wa majini ndi matenda.

Mapeto:

Kuyeretsa mchere, ngakhale kuti sikungathe kulekanitsa mchere woyera ndi madzi mwachindunji, kungakhale njira yofunika kwambiri yothandizira njira yolekanitsira mchere. Pogwiritsa ntchito kuyeretsa mchere pang'ono, n'zotheka kulekanitsa mchere pang'ono ndi madzi. Komabe, kuyeretsa kwathunthu sikungatheke kudzera mu njira iyi yokha, chifukwa sikuchotsa zonyansa zonse. Ngakhale kuti pali zofooka zake, kuyeretsa mchere kukupitirizabe kukhala chida chamtengo wapatali m'magwiritsidwe osiyanasiyana asayansi ndi mafakitale, zomwe zimathandiza kulekanitsa ndi kuyeretsa zinthu zosiyanasiyana.
