鸡血清(无菌过滤)200ml

鸡血清(无菌过滤)200ml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。

In order to measure the concentration of PKCa in the sample, this PKCa ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus PKCa concentration. The concentration of PKCa in the samples is then determined by comparing the O.D. of the samples to the standard curve.Sample collection and storagesSerum - Use a serum separator tube and allow samples to clot for 30 minutes before centrifugation for 10 minutes at approximately 3000×g. Remove serum and assay immediately or aliquot and store samples at -20℃ or -80℃.Avoid repeated freeze-thaw cyclesPlasma - Collect plasma using EDTA or heparin as an anticoagulant.

Add standard 50μl to standard well.3.  Add Sample: Add testing sample 10μl then add Sample Diluent 40μl 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 0.1 pmol/L6. 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!

Add standard 50μl to standard well.3.  Add Sample: Add testing sample 10μl then add Sample Diluent 40μl 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 5.0 ng/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!
