| Description | The Immortalized Adult Mouse Dorsolateral Prostate Cells (INK4 -/- DLP) were derived from a subline of the INK4a mouse, a transgenic knockout that lacks p16INK4a and p19ARF. Both p16INK4a and p19ARF are specific inhibitors of cyclin-dependent kinases Cdk4 and Cdk6 that regulate cell cycle progression. The cells were isolated from the dorsolateral prostate (DLP), which has simple cuboidal epithelium that is somewhat folded. The luminal secretory cells in the epithelium secrete a homogenous eosinophilic substance into the lumen of the DLP. This cell line is a useful model for studying the prostate stroma-epithelium signalling way, which plays an important role in prostate development and cancer progression. |

| I want to make sure these cells express my gene of interest before I decide to buy the cell line. Can you provide a sample so this can be tested? | |
We do not carry out downstream characterization or gene expression profiling of our cell lines. To facilitate your preliminary experiments we can provide an RNA extraction (0.5ug total RNA) or cell lysate (100ug/100ul provided in 62.5mM Tris‐HCl, 2% SDS, 10% Glycerol, 50mM DTT, 0.01% w/v Bromophenol Blue) for any of our immortalized cell lines for a small fee. Please inquire directly for more information. The lead time will be around 2 weeks from the time of placing an order (if the item is in stock). | |
| How often do I need to change the media? | |
The media should be changed every 2-3 days. | |
| Why do these cells need bio safety level II? | |
In order to be more cautious, we follow the CDC-NIH recommendations that all mammalian sourced products should be handled at the Biological Safety Level 2 to minimize exposure of potentially infectious products. This information can be found in "Biosafety in Microbiological and Biomedical Laboratories" (1999). Your institution"s Safety Officer or Technical Services will be able to make the call as to whether BioSafety Level I is possible with these cells at your site if required. | |
| Do you sell ECM coated T75 flasks? | |
Yes we can provide a coating service. Please inquire with [email protected] | |
| Is it necessary that we have to use the recommended T25 ECM-coated flasks for growing the cells? Can we use normal ECM coated 60mm/90mm petri plates for growing the cells? | |
We strongly recommend using G299 T25 flasks to ensure recovery of these cells before testing other plates. | |
| What can I coat a larger dish to subculture? | |
We also offer applied extracellular matrix (collagen type I) in liquid form, for the coating of larger flasks and other required plasticware: http://www.abmgood.com/Applied-Cell-Extracellular-Matrix-G422.html | |
| How long can I store frozen vials for? | |
Cells that are properly frozen using an effective cryoprotective agent can be stored in liquid nitrogen indefinitely without affecting their recovery. | |
| When are cells plated for live cell shipments? | |
1 day prior to shipping | |
| Should the cap of the flask be changed before starting the cell culturing step? | |
No, there is no need in sterile biosafety cabinets unless it has contacted any non-sterile condition (e.g. touching the contaminated tip, etc.). | |
| What is the recommended storage temperature? | |
In general, if you received:Live cells: acclimatize for 3-4 hrs at at the recommended conditions stated for the cell line under the propagation section, and then change media afterwards.Frozen cells: Immediately place cells in liquid nitrogen; -180C. | |
| How is cell density crucial for drug selection? | |
If antibiotic selection is applicable to the target cells, we suggest getting rid of all the background cells so that the cell density is kept lower (even 20-30%). However, once the clones are selected by clonal dilution, we don"t need the drug to still be present. If needed, the cell density should be towards the higher end since cells are already selected. Any primary cells still present will be depleted as a result of senescence and the cell population that remains will be resistant to the specific antibiotic. | |
| My cells are not detaching, what method do you recommend to trypsinize the cells? | |
1. Incubate the coated plate containing trypsin solution at recommended temperature indicated in the propagation section for 3-5 min till the cells round up, monitoring from time to time under microscope.2. Diluting G422 (1:1) with PBS and coating for lesser time. Sometimes the collagen content in G422 is higher and thus make stronger bonding with cells.3. You can try reducing the incubation time as well for coating the plate to make a thinner layer. | |
| Why is it important to determine the optimal seeding density? | |
The seeding density we recommend is for when cells are plated to a new vessel. The optimal seeding density should allow cells to attach to the surface and have room to proliferate.If you seed too little, cells may not attach well to the surface (for adherent cells). Seeding density is important as many cells (adherent or suspension cells) need to be in close proximity for better growth. Cell-cell interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is essential for the survival of the cell. In other cases, if the seeding density is too low, cells may attach but a retardation in cell growth is observed.If you seed too high, the cells will attach but there is insufficient room for further proliferation and they will stop replicating. | |

虽然没有具体用过检测这个抗原的抗体，但是如果希望抗体特异性好点，能检测丰度低的蛋白，还是选Abcam吧，Santa有时候全凭人品了，内参抗体什么的还能凑活，其他的比较勉强。
我觉得封闭这一步时间长短多少并不能减少背景…背景过深多半还是抗体浓度过大…不管一抗还是二抗过大都会使背景加深…一抗的浓度不一定是条带清晰就是最佳了…联系进一步优化一下
这个主要还是抗体的问题，WB最主要的还是要选择一个特异性较好的抗体，抗体是整个实验的重中之重
各位大神，有谁做WB，选用球虫的GADPH作为内参？知道哪个公司有针对球虫内参的抗体？
所以免疫组化在组织定位和定性上比较准确，但是在定量上不够准确。
western blot也是利用抗体和抗原之间的结合具有高度的特异性。经过聚丙烯酰胺凝胶电泳分离的蛋白质样品，转移到固相载体上，固相载体以非共价键形式吸附蛋白质，且能保持电泳分离的多肽类型及其生物学活性不变。以固相载体上的蛋白质或多肽作为抗原，与对应的抗体起免疫反应，再与酶或同位素标记的第二抗体起反应。
western blot因为有内参标定，所以在定量上要更加准确。但是在组织定位上不如免疫组化
一.样本种属来源：
首先要考虑的就是实验样本来源于什么物种。
1、哺乳动物的组织或者细胞样本，通常选择β-actin、β-tubulin、GAPDH、Lamin B、Histone H3、Na,K atpase等。
2、植物来源实验样本，则可以选择plantactin、Rubisco等。
3、其他来源样本研究较少，所以就应该参照文献报导，选择合适的蛋白作为内参。
二.目的蛋白分子量：
选择内参抗体时，应该考虑目的蛋白分子量的大小。通常应该保证目的蛋白与内参蛋白分子量相差5KD以上。比如目的蛋白分子量为45KD，此时不适宜选择β-actin作为内参，可以考虑选择GAPDH或者β-tubulin作为内参。
三.目的蛋白表达部位：
就一般的蛋白检测来说，β-actin、β-Tubulin抗体等就可以了，而针对于核蛋白的定量，特别是样本蛋白就是核蛋白时，选择恰当的核蛋白内参则更能体现内部参照的价值。常用的核内参抗体有Lamin A、Lamin B、Histone H3，除此之外，其它常见的核蛋白内参还有PCNA、K70、K80等，在一些文献报道中，Erk2、TATA binding protein(TBP)以及c-Jun、c-Fos等都有使用。而对于膜蛋白检测，常用的内参抗体为Na,K ATPase。对于线粒体蛋白的检测，常用VDAC1和COX IV作为内参抗体。
以上几条原则只是针对通常情况，但是需要注意的问题是——内参的选择需要考虑实际的试验环境，比如某些细胞中，由于组织缺氧、糖尿病等因素会导致GAPDH的表达增高，不适合做内参。比如在涉及细胞增殖相关试验中，c-Jun由于自身表达变化就不适合做内参;而在凋亡实验时，TBP、Lamin等也不适合作为内参。因此设计实验方案的时候应该考虑这些因素并查询相应文献，在实验过程中也应该注意如果内参表达出现异常，应考虑这方面因素。
