Product Specifications:
Item# 1021: Recombinant HIV-1 MN Envelope Glycoprotein gp120 (Baculovirus).
Concentration: See vial
Mass/vial: 100ug
Diluent: PBS
Purity: >95%
Stabilizer: None
Preservative: None
Storage: -75°C
Physical State: Frozen
Liquid Stability: At least 24 months at -75°C.
Applications: Human diagnostics, CD4 binding, Drug screening, Human T-cell CD4 studies.
Description: Gene cloned from T-cell-tropic HIV-1 MN strain and the full length recombinant envelope gp120 glycoprotein produced in the Baculovirus Expression System.
Purification: This protein is purified by immuno-affinity chromatography to >95% purity as determined by SDS-PAGE, reduced.
Specificity: This protein binds to murine monoclonal antibodies of defined epitope specificity and HIV-1 converted human serum polyclonal antibodies in ELISA and Western ELISA.
Biological Activity: This protein binds to human T-cell receptor CD4 in ELISA and Western ELISA as determined by CD4/gp120/Anti gp120 mAb-peroxidase capture ELISA. This protein activates human T-Lymphocytes (CD4+, CD4-), in vitro, as measured by RNA synthesis during G0 to G1 transition phase of antigen-binding competent cells.
Application and Instructions for use:
Recommended concentrations for use are approximate values. A dose dependent response assay should be performed to determine the optimal concentration for use in specific applications. ELISA and Western ELISA require 10-100ng protein depending on the nature and affinity of the detection reagent. Human serum polyclonal antibodies yield titers of 1:1000 or greater at 10-100ng of immobilized protein under standard ELISA conditions.

有没有朋友使用碧云天的细胞衰老β-半乳糖苷酶染色试剂盒做过细胞衰老，本人小白，求相关细胞处理的过程及数据分析方法。贴壁细胞六孔板需要接种多少，染色后怎样计数进行数据处理。谢谢啦！

下面的这段话是图注，图注的意思我明白，但是我想知道merge后的图看什么颜色的荧光，蓝色是细胞核，红色是lysosome(位于胞质），绿色是AMPKβ2，该实验是想观察AMPKβ2是否转位到lysosome上了，如果确实发生了AMPKβ2转位到lysosome上，那么merge后是红色与绿色融合在一起，是吗？融合在一起发什么颜色的光了？
免疫组织化学又称免疫细胞化学，是指带显色剂标记的特异性抗体在组织细胞原位通过抗原抗体反应和组织化学的呈色反应，对相应抗原进行定性、定位、定量测定的一项新技术。它把免疫反应的特异性、组织化学的可见性巧妙地结合起来，借助显微镜的现像和放大作用，在细胞，亚细胞水平检测各种抗原物质，并可在原位显示相应的基因和基因表达产物。免疫组织化学技术现已有：免疫荧光组织（细胞）化学技术、免疫酶组织（细胞）化学技术、亲和组织化学技术、免疫金银及铁标记免疫组织化学技术等。免疫荧光组织（细胞）化学技术是采用荧光素标记的已知抗体（或抗原）作为探针，检测待测组织、细胞标本中的靶抗原（或抗体），形成的抗原抗体复合物上带有荧光素，在荧光显微镜下，由于受高压汞灯光源的紫外光照射，荧光素发出明亮的荧光，这样就可以分辨出抗原（或抗体）的所在位置及其性质，并可利用荧光定量技术计算抗原的含量。以达到对抗原物质定位、定性、定量测定的目的。
最近开始做TUNEL染色，第一次按罗氏protocol做的，阴性对照是没有显色的。没做阳性对照。第二次、第三次做出来背景都很深，肾小管每个细胞核上都染上了棕黄色，DAB染色很快，几秒就变一片黄。具体步骤是：1烤片脱蜡至水2.蛋白酶K20ug/ML37℃10分钟3.tunel液冰上配置后加组织上，37度1h。4.pod液37℃30min5.DAB显色。在蚂蚁淘中检索后，优化了实验条件，在蛋白酶K前加了3%H2O2封闭10min，缩短了tunel液至40min。这是第三次的结果大家帮我看看
这是对照组
这是模型组
