 'Ōlelo Aʻo: Ke hoʻohana nei i ka media moʻomeheu cell a me ka polylysine-coated plates e kākoʻo i ka hoʻokumu ʻana a me ka mālama ʻana i nā ʻōnaehana hōʻike e like me HEK293, i hui pū ʻia me nā transporter buffers ma nā ʻano pH like ʻole a me HBSS e hoʻoponopono i ke ʻano o ka transport assay environment, a me ka hoʻohui hou ʻana i nā buffers vesicle reaction, MgATP/MgAMP energy system, a me nā kānana microporous a me ka hoʻopau ʻana i nā kānana vesicle. ka hoʻāʻo ʻana i ka hoʻopau ʻana, ka hoʻokaʻawale ʻana, a me ka ʻike ʻana, a laila e ʻae ai i ka loiloi in vitro maʻamau o ka hana efflux transporter (me MDR1, BCRP, a me BSEP) a me ka lāʻau-drug interaction (DDI) pilikia.

ʻO nā vesicle transporter ABC, e like me ka MDR1 vesicles, BCRP vesicles, a me BSEP vesicles, e hāʻawi i ka standardized in vitro platform no ka loiloi ABC transporter efflux activity in HEK293-based expression system. Hoʻohana nui ʻia kēia mau ʻōnaehana i nā ʻano hoʻokolohua vesicular transport assay e noiʻi i nā mīkini lawe membrane ma lalo o nā kūlana hoʻokolohua i hoʻomalu ʻia. Efflux transporter vesicle kit formats, me Transporter Control Vesicles, e hōʻoia i ka kikoʻī o ka assay, reproducibility, a me ka hoʻokō kānāwai. Hāʻawi ʻo Iphase i nā ʻōnaehana lawe lāʻau e hoʻokō me ka FDA a me EMA Guidance for Drug Interaction Studies.

MDR1 vesicles i ka ABC transporter efflux a me ka vesicular transport assay

MDR1 vesiclesHoʻohana nui ʻia e hōʻike i ka hana efflux transporter ABC i nā ʻōnaehana hoʻokele vesicular transport assay. Ma HEK293-mau hoʻohālike hoʻohālike, MDR1 vesicles e hoʻopili ikaika i ka hoʻokuʻu ʻana i ka substrate, e hōʻike ana i kahi hana efflux kiʻekiʻe e pili ana i ka waiho ʻana a me ke kū'ē.

ʻO nā vesicles MDR1 nā mea hana pono no ke aʻo ʻana i ka hana efflux transporter a me ka kikoʻī o ka substrate. Hoʻohana nui ʻia lākou i nā noiʻi Drug Interaction e loiloi i ka lāʻau-drug interaction (DDI) hiki i ka wā mua o ka hoʻomohala lāʻau.

Hāʻawi nā Efflux transporter vesicle kit format i loaʻa nā vesicle MDR1 i nā ʻōnaehana maʻamau a hana hou ʻia no ka loiloi hana transporter.

ʻO nā vesicles BCRP i nā ʻōnaehana kit vesicle transporter efflux

BCRP vesicleshe mau mea nui o ka ABC transporter efflux system in HEK293-based vesicular transport assay platforms. Ma ke ʻano he transporter efflux koʻikoʻi, hoʻololi nui ka BCRP i ka bioavailability o ka lāʻau a me ka hāʻawi ʻana i nā kiko.

Ma nā haʻawina efflux transporter, hoʻohana ʻia nā vesicles BCRP e helu i ka hana halihali substrate a me ka hiki ke pale. Hoʻohana nui ʻia kēia mau assays i loko o nā noiʻi Drug Interaction no ka loiloi ʻana i ka lāʻau-drug interaction (DDI) pili i ka transporter-mediated clearance.

Hāʻawi nā ʻōnaehana vesicles Efflux transporter vesicle e hoʻopili ana i nā vesicle BCRP i nā mea paʻa a hiki ke hoʻonui ʻia no ka pharmacokinetic a me ka transporter profiling.

ʻO nā vesicles BSEP i ka ABC transporter efflux a me ka loiloi palekana

BSEP vesiclesHoʻohana mua ʻia e loiloi i ka hana efflux transporter ABC hepatic ma HEK293-mau ʻōnaehana hoʻokele vesicular transport assay. He kuleana koʻikoʻi ka BSEP i ka lawe ʻana i ka waikawa bile a me ka homeostasis ate.

Ma nā haʻawina efflux transporter, hoʻohana ʻia nā vesicles BSEP e loiloi i ka halihali substrate a me ka inhibition, he mea nui ia no ka wānana ʻana i ka lāʻau - Pono maʻamau kēia mau loiloi i nā noiʻi Drug Interaction a me nā hoʻouna hoʻoponopono e pili ana me ke alakaʻi ICH-M12.

Hāʻawi ʻia nā ʻōnaehana vesicles Efflux transporter vesicles i loaʻa nā vesicles BSEP i nā mea hana maʻamau no ka loiloi palekana hepatic.

N&A

Q1: He aha ka ABC transporter vesicles i hoʻohana ʻia no?
Hoʻohana ʻia nā vesicle transporter ABC no ka loiloi ʻana i ka ATP-hilinaʻi i ka hana efflux transport in vitro, kākoʻo i nā haʻawina e pili ana i ka kikoʻī o ka substrate, ka pāpā ʻana i ka mea lawe, a me ka lāʻau-drug interaction (DDI) pilikia i ka wā o ka hoʻomohala ʻana i ka lāʻau.

Q2: No ke aha e koi ʻia ai ʻo MgATP i nā hoʻokolohua vesicular transport assays?
Hāʻawi ka MgATP i ka ikehu e pono ai no ka hoʻoulu ʻana i nā mea halihali ABC e like me MDR1, BCRP, a me BSEP, e hiki ai i ka halihali substrate ikaika; Hoʻohana maʻamau ʻia ʻo MGAMP ma ke ʻano he mana maikaʻi ʻole e hoʻokaʻawale i ka lawe ʻana mai ka diffusion passive.

Q3: He aha ke kuleana o nā ʻokoʻa pH transporter buffers i kēia mau hoʻokolohua?
Hiki i nā mea hoʻokele kaʻa ma nā ʻano pH like ʻole ke hoʻololi i ka hana transporter a me ka ionization substrate, e ʻae ana i nā kūlana kūpono a pili pono i ke kino, no ka pH-nā mea lawe maʻalahi e like me BCRP.

Q4: No ke aha i hoʻohana ʻia ai nā papa polylysine-coated i nā haʻawina transporter?
Hoʻonui ka Polylysine - nā papa i uhi ʻia i ka cell adhesion a me ke kūpaʻa, ʻo ia ka mea koʻikoʻi no ka mālama ʻana i ka ʻōlelo a me ka hana o nā protein transporter i loko o ka cell-based assays e like me nā ʻōnaehana HEK293.

Q5: Pehea e kākoʻo ai nā ʻike hoʻokele vesicular i nā koi hoʻoponopono e like me ICH M12?
Hāʻawi ka Vesicular transport assays i ka ʻikepili maʻamau, reproducible ma ka transporter-mediated drug interactions, he mea nui ia no ka hoʻouna ʻana i nā hoʻoponopono ma lalo o nā alakaʻi FDA, EMA, a me ICH M12 no ka loiloi pilikia DDI.
