Description
Q-PAGE™ TGN (Tris-Glycine Novel) Precast Gels are ready-to-use acrylamide gels for SDS-PAGE running in Tris-Glycine buffer system. With unique formula, Q-PAGE™ TGN Precast Gels perform enhanced speed, better separation, and longer shelf life as compared with conventional Laemmli Tris-HCl gels. The protein migration patterns in Q-PAGE™ TGN series, however, are similar with typical Laemmli Tris-HCl gels, and thus Q-PAGE™ TGN Precast Gels are compatible to traditional SDS-PAGE and subsequent analyses.
Q-PAGE™ TGN Precast Gels are available in gradient (4 to 15%) and fixed (10%) concentrations of polyacrylamide in 12- and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP4XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP5XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.

Recommendations/Tips for Gel Running
1. Remove comb and tape before adaption.
2. Use fresh 1X running buffer for the inner cathode chamber.
3. Rinse the wells before sample loading.
4. Try 200 V first, and optimize the voltage and running time if needed. Do not set voltage lower than 100 V.
Sample Preparation for SDS-PAGE
1. Mix protein sample with 2X sample buffer.
2. Heat the diluted samples at 95°C for 5 min or at 70°C for 10 min.
3. Cool the diluted samples to 4°C and spin down the water condensed on tube surface. (If there is high viscosity part at bottom of tube, transfer supernatant to a new tube.)
Prepare Q-PAGE™ for Sample Loading
1.Open the blister tray of Q-PAGE™ Precast Gel.
2.Briefly rinse the gel cassette with ddH2O.
3.Remove tape and comb; avoid squeezing the gel.
4.Adapt Q-PAGE™ to electrophoresis system; instruction are provided below. (BioRad Mini-PROTEAN® Core Electrophoresis System is recommended.)
5.Use a pipette to gently wash the wells with running buffer to remove residual storage buffer.
6.Fill the wells with running buffer prior to sample loading.
7.Load samples and pre-stained protein marker into numbered wells.
8.Fill both inner and outer chambers with running buffer to the highest level. Ensure gel wells are completely covered.

40-50 mA 10-20 mA |
50-60 mA 25-30 mA |
80-90 mA 35-40 mA |
90-100 mA 40-50 mA |
Expected temperature | 25-30°C | 25-40 °C | 25-40°C | 25-40°C |
*1 Set voltage higher than 100 V is recommended
*2 Try 200 V first, and optimize the voltage and running time if needed.
*3For higher voltage conditions, please use fresh running buffer for inner and outer chambers
*4 Running time varies depending on gel percentage, running buffer, temperature, and power supply.
Remove Q-PAGE™ Gel from Cassette
Open cassette immediately after electrophoresis. Avoid gel drying.
1.Insert the cassette opener into corners of cassette.
2.Sequentially pry the opener to separate the two plates.
3.Gently pull two plates apart from the top of cassette.
4.Carefully detach the gel either from the bottom or the top side of the cassette.
-Avoid diagonally peeling the gel from the corner.
-Use water to help gel detachment if needed.
5.Gently remove the gel for further staining or Western blotting.

大多数药物在体内都是和特异性受体相互作用，改变细胞的生理生化功能而产生效应。目前已经确定的受体有30多种，根据受体存在的标准，受体可大致分为三类：
1．细胞膜受体：位于靶细胞膜上，如胆碱受体、肾上腺素受体、多巴胺受体、阿片受体等。
2．胞浆受体：位于靶细胞的胞浆内，如肾上腺皮质激素受体、性激素受体。
3．胞核受体：位于靶细胞的细胞核内，如甲状腺素受体。
另外也可根据受体的蛋白结构、信息转导过程、效应性质、受体位置等特点将受体分为四类：
1．含离子通道的受体（离子带受体）：如N-型乙酰胆碱受体含钠离子通道。
2．G蛋白偶联受体：M-乙酰胆碱受体、肾上腺素受体等。
3．具有酪氨酸激酶活性的受体：如胰岛素受体。
4．调节基因表达的受体（核受体）：如甾体激素受体、甲状腺激素受体等。
有些受体具有亚型，各种受体都有特定的分布部位核特定的功能，有些细胞也有多种受体。
现在有一个实验需要看一种药物与受体的结合情况，想咨询一下放射性配体受体结合实验，因为我们不具备这个实验条件，最好能外包那种
受体是细胞在进化过程中形成的细胞蛋白组分，能识别周围环境中某种微量化学物质，首先与之结合，并通过中介的信息转导与放大系统，触发随后的生理反应或药理效应。自从Langley 提出受体学说100年后，受体已被证实为客观存在的实体，类型繁多，作用机制多已被阐明，现在受体已不再是一个空泛笼统的概念。受体分子在细胞中含量极微，1mg 组织一般只含10fmol左右。能与受体特异性结合的物质称为配体(ligand)。受体仅是一个“感觉器”，对相应配体有极高的识别能力。受体-配体是生命活动中的一种偶合，受体都有其内源性配体，如神经递质、激素、自身活性物(autocoid)等。能激活受体的配体称为激动药(agonist)，能阻断其活性的配体称为拮抗药(antagonist)。根据受体与配体结合的高度特异性，受体被分为若干亚型，如肾上腺素受体又分为α1、α2、β1和β2等亚型，其分布及功能都有区别。受体与配体有高度亲和力，多数配体在1pmol～1nmol/L的浓度时即可引起细胞的药理效应。反应之所以如此灵敏主要是靠后续的信息转导系统，如细胞内第二信使(second messenger)的放大、分化及整合功能。酶、载体、离子通道及核酸也可与药物直接作用，但这些物质本身具有效应力，故严格地说不应被认为是受体。某些细胞蛋白组分可与配体结合，但没有触发效应的能力，称为结合体(acceptor)。
请教各位大神，我最近在做WB，565KD的蛋白，动物组织的样品，听说样品制备需要蔗糖裂解液，请问这个是必须的嘛？用一般蛋白提取方法制备可以吗？还有电泳和转膜条件能否分享一下。不胜感激
