Soluble Lyophilized Silk Fibroin Short Description: This product can keep stable for more than 18 months at room temperature. The regenerated silk solution remains the same structural transition capability from random coil anda-helix structure to B-sheet structure as original silk solution. Product Detail Product Tags Brand Name: Fancci Alternative Name: Freeze-dried silk fibroin Introduction: Large molecular weight silk fibroin in aqueous solution can be processed into different solid material formats. Unfortunately, the purified silk solution can’t be stored or transported for a long time as silk undergoes structural changes and aggregates due to thermodynamic instability. Our proprietary lyophilized silk product completely solve these problems and the lyophilized silk can be dissolved in water or buffer at high concentration, facilitating downstream material processing. Lyophilized silk in a glass vial presents to be a white porous sponge. Since the vial is completely sealed, lyophilized silk can remain stable for a long period of time (> 18 months) at room temperature in terms of appearance, solubility, molecular weight distribution and structure. The regenerated silk solution remains the same structural transition capability from random coil anda-helix structure to B-sheet structure as original silk solution, which is critical in preparation of solid material formats. Table 1 Parameter, testing and method of lyophilized silk fibroin Operation method: Lyophilized silk fibroin can be stored at room temperature for 18 months. Before use, water or buffer or cell/drug solution can be added into the sterile glass bottle using a needle syringe (keep sealed) or a pipette (open bottle). The lyophilized silk cake in the bottle can be quickly rehydrated forming a light yellow solution and the silk concentrations obtained can reach up to 30-40%. Application: Same as the solution after purification, the soluble lyophilized silk fibroin can also be used as a basic raw material for fabrication of many biomedical products. Furthermore, soluble lyophilized silk fibroin has advantages of longer and ambient storage, easier transportation and higher concentration of regenerated solution compare to regular silk fibroin solution.

Intuaslagtha Lyophilized Silk Fibroin Cur síos achomair: Is féidir an táirge a choinneáil seasmhach ar feadh níos mó ná 18 mí ag teocht an tseomra. Tá an réiteach síoda athghinte an cumas aistriú struchtúrach céanna acu ó corn randamach struchtúr anda-helix a B-chláir struchtúr mar réiteach síoda bunaidh. Sonraigh Táirge Táirge Clibeanna B Rand Ainm: Fancci Ainm Malartach: Reo-triomaithe fibroin síoda Réamhrá : Is féidir le Móra fibroin meáchan síoda móilíneach i dtuaslagán uiscí a phróiseáil i bhformáidí ábhair éagsúla soladach. Ar an drochuair, ní féidir leis an réiteach síoda íonaithe a stóráil nó a iompraítear ar feadh i bhfad mar a chuirtear faoi síoda athruithe struchtúir agus comhiomláin mar gheall ar éagobhsaíocht teirmidinimice. Ár táirge síoda dílseánaigh lyophilized a réiteach go hiomlán ar na fadhbanna agus is féidir leis an síoda lyophilized a thuaslagadh in uisce nó Maolán ag tiúchan ard, a éascú a phróiseáil ábhar sruth. Cuireann síoda lyophilized i vial gloine a bheith ina spúinse scagach bán. Ós rud é go bhfuil an vial séalaithe go hiomlán, is féidir le síoda lyophilized fós seasmhach ar feadh tréimhse fada ama (> 18 mí) ag teocht an tseomra i dtéarmaí cuma, tuaslagthacht, dáileadh meáchan móilíneach agus struchtúr. Tá an réiteach síoda athghinte an cumas aistriú struchtúrach céanna acu ó corn randamach agus a struchtúr -helix a B -sheet struchtúr mar réiteach síoda bunaidh, rud atá ríthábhachtach á hullmhú formáidí ábhar soladach. Tábla 1 Paraiméadar, tástáil agus modh fibroin síoda lyophilized O Modh peration: Is féidir le fibroin síoda lyophilized a stóráil ag teocht an tseomra ar feadh 18 mí. Sula n-úsáidtear, uisce nó Maolán nó is féidir tuaslagán cill / druga a chur leis isteach sa bhuidéal gloine steiriúla baint úsáide as steallaire snáthaid (choinneáil séalaithe) nó pípéad (buidéal oscailte). Is féidir leis an císte síoda lyophilized sa bhuidéal a rehydrated go tapa dteacht ar réiteach buí éadrom agus na tiúchain síoda fhaightear féidir teacht suas le 30-40%. A pplication : Mar an gcéanna le an réiteach i ndiaidh íonú, is féidir leis an fibroin síoda intuaslagtha lyophilized a úsáid freisin mar ábhar bunúsach amh le haghaidh monaraithe de tháirgí bithleighis leor. Ina theannta sin, tá intuaslagtha fibroin síoda lyophilized buntáistí níos faide agus a stóráil comhthimpeallach, iompar níos éasca agus tiúchan níos airde de thuaslagán athghinte a chur i gcomparáid le réiteach síoda fibroin rialta.
