Add standard 50μl to standard well.3.  Add Sample: Add testing sample 10μl then add 40μl of Sample Diluent to testing sample well; Blank well doesn’t add anyting.4.  Add 100μl of HRP-conjugate reagent to each well, cover with an adhesive strip and incubate for 60 minutes at 37°C. 5.  Aspirate each well and wash, repeating the process four times for a total of five washes. Wash by filling each well with Wash Solution (400μl) using a squirt bottle, manifold dispenser or autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Solution by aspirating or decanting. Invert the plate and blot it against clean paper towels.6.  Add chromogen solution A 50μl and chromogen solution B 50μl to each well. Gently mix and incubate for 15 minutes at 37°C. Protect from light.7.  Add 50μl Stop Solution to each well. The color in the wells should change from blue to yellow. If the color in the wells is green or the color change does not appear uniform, gently tap the plate to ensure thorough mixing.8.  Read the Optical Density (O.D.) at 450 nm using a microtiter plate reader within 15 minutes.Calculation of results1. This standard curve is used to determine the amount in an unknown sample. The standard curve is generated by plotting the average O.D. (450 nm) obtained for each of the six standard concentrations on the vertical (Y) axis versus the corresponding concentration on the horizontal (X) axis. 2. First, calculate the mean O.D. value for each standard and sample. All O.D. values, are subtracted by the mean value of the zero standard before result interpretation. Construct the standard curve using graph paper or statistical software. 3. To determine the amount in each sample, first locate the O.D. value on the Y-axis and extend a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the X-axis and read the corresponding concentration. 4. Any variation in operator, pipetting and washing technique, incubation time or temperature, and kit age can cause variation in result. Each user should obtain their own standard curve.5. The sensitivity by this assay is 1.0 pg/ml6. Standard curve  Storage:  2-8℃.validity: six months.  FOR RESEARCH USE ONLY; NOT FOR THERAPEUTIC OR DIAGNOSTIC APPLICATIONS! PLEASE READ THROUGH ENTIRE PROCEDURE BEFORE BEGINNING!

猪血清(无菌过滤)100ml

猪血清(无菌过滤)100ml以下是关于猪血清(无菌过滤)的相关介绍:基本信息定义:猪血清是猪血在凝固后,经离心或自然沉淀,去除上层血浆和下层血细胞等成分,得到的淡黄色透明液体。无菌过滤则是通过特定的过滤技术和设备,去除猪血清中的细菌、真菌、支原体等微生物,使其达到无菌状态,可用于细胞培养、生物制药等对无菌条件要求较高的领域。外观:正常情况下为淡黄色透明液体,颜色可能因猪的品种、饮食、采血时间等因素而略有差异。制备过程采血:使用无菌干燥玻璃容器从屠宰场采集猪血,盛取猪血前玻璃容器中可加入无菌生理盐水和适量抗生素,如庆大霉素,以防止细菌污染。静置与离心:将采集的猪血在 4℃冰箱静置数小时,待血清自然析出,然后进行离心,通常以 4000rpm 离心 15 分钟左右,进一步分离血清和血细胞等杂质,回收上清液,即得到初步的猪血清。无菌过滤:将初步得到的猪血清通过正压过滤器,使用 0.22μm 或 0.1μm 的滤膜进行过滤除菌,以去除血清中的细菌、真菌和支原体等微生物,得到无菌过滤的猪血清。分装与保存:将无菌过滤后的猪血清进行分装,一般以 100ml / 瓶等规格分装,然后置于 - 20℃冰箱保存备用。作用与用途细胞培养:为细胞提供基本营养物质,如氨基酸、维生素、无机物、脂类物质、核酸衍生物等,是细胞生长必需的物质;还能提供激素和各种生长因子,如胰岛素、肾上腺皮质激素、成纤维细胞生长因子等,促进细胞的生长、增殖和分化。生物制药:在疫苗生产中,如猪肺炎支原体疫苗的生产,猪血清是重要的原材料之一;用于配置各种生物制药所需的培养基和缓冲液等,保证药物生产过程中细胞或微生物的生长和代谢需求。科研实验:在免疫学研究、细胞生物学研究、分子生物学研究等领域广泛应用,可用于研究细胞的生理功能、代谢途径、信号传导等,以及作为免疫检测的试剂或样本,用于检测抗体、抗原等。保存方法低温保存:长期保存的猪血清必须储存于 - 20℃至 - 70℃低温冰箱中,4℃冰箱中保存时间切勿超过 1 个月。预留空间:由于血清结冰时体积会增加约 10%,因此在冻入低温冰箱前,必须预留一定体积空间,否则易发生污染或玻璃瓶冻裂。解冻方法:瓶装血清解冻需采用逐步解冻法,即先将 - 20℃至 - 70℃低温冰箱中的血清放入 4℃冰箱中溶解 1 天,然后移入室温,待全部溶解后再分装,在溶解过程中需不断轻轻摇晃均匀,使温度与成分均一,减少沉淀的发生。

鸡血清(无菌过滤)500ml

鸡血清(无菌过滤)500ml鸡血清(无菌过滤)是一种在科研和生物医学领域有着广泛应用的产品,以下是其详细介绍:制备:通常采用健康鸡血液为原料,经无菌采集、分离后,再通过微孔过滤分装而成。例如,先将鸡血用离心机离心,收集滤过液并冻存,数天后取出化冻,经粗滤澄清,*后用灭菌的滤板进行过滤除菌,从而得到无细菌、真菌、支原体等的无菌鸡血清。成分:血清是血浆中不含纤维蛋白原的胶状液体,主要由水和各种化学成分组成,包括白蛋白、α1、α2、β、γ - 球蛋白,甘油三酯,总胆固醇,谷丙转氨酶等。作用:提供基本营养物质:为细胞培养提供氨基酸、维生素、矿物质等多种营养成分,满足细胞生长和代谢的需求。提供激素和生长因子:含有胰岛素、生长激素等激素以及多种生长因子,能够促进细胞的增殖和分化。提供结合蛋白:如转铁蛋白可结合铁离子,为细胞提供铁元素;白蛋白可结合脂肪酸、激素等物质,维持其在培养基中的稳定性和活性。提供促接触和伸展因子:使细胞能够更好地贴壁生长,免受机械损伤,有助于细胞在培养容器表面铺展和生长。对培养中的细胞起到保护作用:可以中和有毒物质,减少细胞氧化应激,降低细胞凋亡的发生率,为细胞提供一个相对稳定和安全的环境。应用:适合于单抗研制、原代和传代细胞培养、规模化培养的疫苗生产、生物医学研究、诊断试剂生产等。例如在制备副鸡嗜血杆菌或禽多杀巴氏杆菌等细菌的培养基时,可作为辅料加入,用于细菌抗原的批量生产,提高细菌培养的含菌量。保存和使用:通常保存在 - 20℃,保质期一般为液体 1 年,冻干粉 3 年。使用时,血清从冰冻区中取出后,应置于 2 - 8℃中使之融化,解冻过程中间歇地轻轻摇晃均匀,待全部溶解后再分装或直接使用。完全融解的血清从 4℃拿出,按要求比例(5% - 20%)加基础培养基配置成全培养基,建议置于 4℃冰箱存放并于 1 - 2 周内用完。在使用鸡血清(无菌过滤)时,有少量蛋白质结块析出通常不影响使用,但未融化或融化未经摇匀的血清禁止直接放入高温水浴内加温,同时应减少血清重复冻融,以避免影响其促细胞生长效果。
