Hujayra fabrikasimadaniyat texnologiyasi vaktsinani ishlab chiqish va biofarmatsevtika kabi keng ko'lamli hujayra madaniyatida muhim rol o'ynaydi. Hujayra madaniyati uchun turli yechimlar kerak bo'lib, PBS buferi ulardan biri hisoblanadi.
PBS Fosfat tamponlangan tuz eritmasining inglizcha qisqartmasi. Odatda, faol biologik preparatlar u bilan suyultiriladi va pseudorabies virusi ham u bilan suyultirilishi mumkin. Buning sababi, PBS buferining sozlanishi pH buferlash effekti va tuz muvozanatlash effekti mavjud. Distillangan suvdan foydalanmaslikning sababi shundaki, suv biologik oqsillarning tuzilishi va biologik xususiyatlarini buzadi; oddiy sho'r suv ishlatmaslikning sababi pH ni moslashtira olmasligidir. Shuning uchun biologik hujayralarni yuvish uchun birinchi tanlov PBS buferidir. PBS panatseya emas. Optimal sharoitlarni saqlash biologik faol moddalarning eng to'liq xususiyatlarini saqlab qolishini ta'minlaydi. Ba'zi biologik faol moddalar PBS dan yuqori sharoitlarni talab qiladi. Bunday holda, boshqa ingredientlarni qo'shish kerak.
PBS buferining pH qiymati hujayralar uchun eng mos pH qiymati diapazoni bo'lib, pH qiymati odatda ozgina kislota va ishqorning stimulyatsiyasi ostida o'zgarmaydi. . Umuman olganda, muhitning pH qiymatini o'zgartirish oson, bu hujayralarga juda zararli, ammo PBS buferi hujayralarni sog'lom saqlashi va mos pH qiymati oralig'ida o'sishi mumkin. Hujayra zavodidagi hujayralar PBS buferi bilan yuvilgandan so'ng, chiqindi muhitni olib tashlash mumkin, keyin esa hujayra ko'payishi uchun yangi muhitni almashtirish mumkin.
PBS buferi hujayrada ishlatilishi kerak bo'lgan echimlardan biridir. zavod madaniyati jarayoni. Bundan tashqari, hazm qilish eritmasi va hazm qilishni to'xtatuvchi eritma ham kerak. Ushbu yechimlarning asosiy vazifalari hujayralarni yaxshiroq o'sish holatida saqlashdir.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
