Usoro Electrophoresis na Biochemistry
Electrophoresis bụ usoro nyocha dị oke mkpa na biochemistry ma rụọ ọrụ dị mkpa na ọmụmụ sayensị dị iche iche. Site na iji ụkpụrụ ndị bụ isi nke mmegharị molekul n'ọhịa eletriki, electrophoresis na-eme ka nkewa, ịchọpụta, na nyocha nke ọtụtụ biomolecules dị iche iche, gụnyere protein, nucleic acids, na carbohydrates. Isiokwu a ga-atụle ụkpụrụ ndị bụ isi nke electrophoresis, usoro electrophoresis dị iche iche, ojiji ha na biochemistry, na uru na oke ha.
Ụkpụrụ Ndị Dị Mkpa nke Electrophoresis
Electrophoresis bụ usoro nyocha dabere na ụkpụrụ nke mmegharị nke molekul chajị n'ọhịa eletriki. Mgbe etinyere field eletrik na etiti kwesịrị ekwesị, molekul ndị a na-elekwasị anya ga-agagharị na electrode na chajị dị iche. Ọnụego mbugharị nke molekul ndị a site na etiti dabere na ihe dị iche iche, gụnyere nha na ọdịdị nke molekul, chajị eletriki ha, na njirimara nke etiti na nchekwa ejiri.
A na-ejikarị gel dịka agarose maọbụ polyacrylamide eme electrophoresis, nke na-arụ ọrụ dịka matriks dị iche iche. Gel a na-ekewa molekul dabere na nha na chajị site na usoro nkewa pore. molekul pere mpe na-agagharị ngwa ngwa site na gel karịa molekul buru ibu.
Ụdị Usoro Electrophoresis
E nwere ọtụtụ ụdị usoro electrophoresis e mere iji gboo mkpa nyocha dị iche iche. Lee ụfọdụ n'ime ụdị ndị a na-ahụkarị:
1. Electrophoresis nke jel Agarose
Electrophoresis gel Agarose bụ ụzọ a na-ejikarị ekewapụta nucleic acid dịka DNA na RNA. Agarose gel na-enye matrix nwere nnukwu pores, nke dabara adaba maka ikewapụ molekul nucleotide dabere na nha ha. A na-emekarị usoro a na pH na-anọpụ iche site na iji ihe nchekwa dịka TAE (Tris-acetate-EDTA) ma ọ bụ TBE (Tris-borate-EDTA).
2. Electrophoresis nke Polyacrylamide Gel (PEEJI)
Polyacrylamide bụ matrix nwere obere oghere karịa agarose, nke na-eme ka ọ dịkwuo irè maka ikewapụ protein na peptide molecules. Enwere ike ime PAGE n'ụdị abụọ bụ isi:
– SDS-PAGE (Sodium Dodecyl Sulfate-PAGE): Na-eji ihe nhicha SDS eme ka protein ndị ahụ dị mfe ma na-agbapụta, ka ha wee na-agagharị dabere na nha molekul naanị. Usoro a bara uru karịsịa maka inyocha oke molekul nke protein ndị ahụ.
– IHU Native-PEAGE: A na-ejikarị ya amụ protein n'ọnọdụ ha ma ọ bụ nke ebumpụta ụwa. Mkpụrụ ndụ ihe nketa na-agagharị dabere na ibu na ọdịdị ha, na-enye ndị nchọpụta ohere ịmụ banyere mmekọrịta protein na ọrụ bayoloji.
3. Isoelectric Lekwasị anya (IEF)
IEF bụ usoro electrophoresis nke na-ekewa molekul, ọkachasị protein, dabere na isi ihe isoelectric ha (pI). Isi ihe isoelectric bụ pH ebe molekul nwere chajị na-anọpụ iche. N'ọhịa eletriki nwere gradient pH, protein ga-akwaga ruo mgbe ha ruru pH kwekọrọ na pI ha, ebe ha na-akwụsị ịkwaga. IEF bara uru karịsịa maka inyocha mgbagwoju protein dị na ngwakọta.
4. Capillary Electrophoresis (CE)
Capillary electrophoresis bụ usoro ọgbara ọhụrụ nke na-eji obere capillaries dị n'obosara kewaa molekul. Ọ na-enye mkpebi dị elu na ọsọ nkewa ngwa ngwa karịa usoro gel ọdịnala. A na-ejikarị CE eme ihe maka nyocha nke obere molekul, amino acid, peptides, na nucleotides.
Ojiji nke Usoro Electrophoresis na Biochemistry
Usoro elektrophoresis na-arụ ọrụ dị oke mkpa n'ọmụmụ ihe dị iche iche gbasara kemịkalụ. Lee ụfọdụ ojiji dị mkpa:
1. Nyocha Asịd Nuklia
A na-ejikarị electrophoresis nke gel Agarose eme ihe na nyocha DNA na RNA. Nke a gụnyere nhazi mmachi, nhicha nke iberibe DNA maka cloning, nyocha nke ngwaahịa PCR, na nkwenye nke ogologo na njupụta nke nucleic acid.
2. Nyocha protein
SDS-PAGE na-ekpuchi ngwa dịka ịchọpụta ibu protein, ime ka akụkụ protein dị ọcha, na ịlele ngosipụta protein recombinant. Enwere ike iji Native-PAGE nyochaa mmekọrịta protein na oligomerization.
3. Proteomics
N'ọmụmụ ihe gbasara proteomics, a na-ejikarị IEF eme ihe dị ka nzọụkwụ mbụ iji kewaa protein dabere na isi ihe isoelectric ha tupu njem nke abụọ site na iji SDS-PAGE. A maara njikọta a dị ka 2D-PAGE ma na-enye ohere nkewa nke ọtụtụ puku protein n'otu nnwale.
4. Nchọpụta na Ahụike
A na-ejikwa electrophoresis eme ihe n'ọhịa ahụike, dịka ọmụmaatụ na electrophoresis nke hemoglobin maka nchọpụta ọrịa anaemia sickle cell ma ọ bụ thalassemia, nyocha protein serum iji chọpụta nsogbu ahụ ji alụso ọrịa ọgụ, na electrophoresis nke mmamịrị maka nchọpụta ọrịa akụrụ.
Uru na Mmachi nke Electrophoresis
Usoro electrophoresis nwere ọtụtụ uru dị iche iche nke na-eme ka ọ bụrụ ihe a ma ama na ụlọ nyocha biochemistry:
– Mkpebi Dị Elu: Nwere ike ikewapụ molekul nwere obere ọdịiche dị na nha ma ọ bụ chajị.
– Dị Mfe ma Dị Irè: Usoro a dị mfe ịtọlite na itinye n'ọrụ, yana akụrụngwa dị ọnụ ala.
– Mgbanwe: Enwere ike iji ya mee ọtụtụ ụdị mkpụrụ ndụ ihe nketa.
Agbanyeghị, electrophoresis nwekwara ụfọdụ ihe mgbochi: +
– Nhọrọ Ọkara: Ọ bụghị mkpụrụ ndụ niile ka a ga-ekewa nke ọma n'ime otu gel.
– Mmetụta uche: Mgbe ụfọdụ, a na-achọ usoro ndị ọzọ dịka ịcha agba iji chọpụta molekul ahụ.
– Nha: Ihe isi ike n'ịgụkọ mkpokọta molekul zuru oke.
Mmechi
Electrophoresis ka bụ otu n'ime ngwaọrụ kachasị mkpa na biochemistry nke oge a. Site na iji ụzọ dịka agarose gel electrophoresis, PAGE, isoelectric focusing, na capillary electrophoresis, ndị nchọpụta nwere ike kewapụ, chọpụta, ma nyochaa ọtụtụ biomolecules nwere oke nkenke. N'agbanyeghị oke ụfọdụ, mkpebi ya dị elu, mfe ya, na mgbanwe ya na-eme ka electrophoresis dị mkpa ma dị mkpa n'ọtụtụ ngwa biomedical na biochemical.
