Description:Mouse monoclonal antibody to human S100A7 (psoriasin)
Purification:Protein G affinity purified
Product Type: Primary antibody
Target Protein:Human S100A7 (psoriasin)
Immunogen:A short peptide (tdyhkqshgaapcsggs) derived from human S100A7 (psoriasin) was conjugated with KLH for immunization.
Fusion Myeloma:Sp2/0-Ag14
Specificity:This antibody is reactive to S100A7 peptide (tdyhkqshgaapcsggs) and GST tagged recombinant S100A7 protein.
Species Reacitvity:Human, others not tested
Host / Isotype:Mouse, IgG1 Kappa
Formulation:Lyophilized from a solution in 0.01M PBS, pH 7.0
Reconstitution:Double distilled water is recommended to adjust the final concentration to 1.00mg/mL.
Storage: Store at -20oC
Research Area:Oncology, psoriasis
Background:
S100A7 is 11 kilo-dalton calcium binding protein with 2 EF motifs. It is also called psoriasin due to its significantly elevated level in the skin lesion of psoriasis. The protein is over-expressed in squamous cell tumors of the skin, lung and breast. S100A7 expression is induced after activation of epidermal growth factor receptor.
Application:
Western blot (see image): This antibody is reactive to 36.85KD GST tagged recombinant S100A7 protein.
The GST tagged recombinant S100A7 was loaded at 200ng/lane. The anti- S100A7 clone 9A4 was used at 1μg/ml, and the HRP conjugated goat anti-mouse IgG was used at 1:2,000 dilution.
ELISA:This antibody is reactive to recombinant S100A7 protein.

酶标仪按照功能的不同划分,可以分为（1）光吸收酶标仪（可见酶标仪，紫外/可见酶标仪）（2）荧光酶标仪（3）化学发光酶标仪。
分光光度计按照波长及应用领域的不同可以分为：（1）可见光分光光度计（2）紫外分光光度计（3）红外分光光度计（4）荧光分光光度计（5）原子吸收分光光度计。
分光光度计和酶标板存在一些不同之处，具体差别体现在以下三个方面：
（1）盛装待测溶液的容器：
分光光度计用的是比色皿，酶标仪使用的是塑料微孔板(酶标板)。比色皿只能起到盛装溶液的作用，每个比色皿一次只能盛装一种溶液。酶标板常用透明的聚乙烯材料制成，对抗原抗体有较强的吸附作用，因此用它作为固相载体，酶标板通常为48孔或96孔，每个微孔可以盛装不同的溶液。
（2）光路的方向：
分光光度计是水平光路，而酶标仪则是垂直光路。由于酶标板盛样本的塑料微孔板是多排多孔的,光线只能垂直穿过,因此酶标仪的光束都是垂直通过待测溶液和微孔板的,光束既可是从上到下,也可以是从下到上穿过比色液。垂直光的特点是标本吸光度受液体浓缩或稀释的影响小，不足之处是受被测样本液面是否水平、酶标板透光性、孔底是否平整等的影响较大。
（3）光路的长度：
由于光密度（OD值）与吸光系数, 待测组分的浓度以及光路长度成正比关系。
分光光度计采用的比色杯的宽度通常是1cm，所以光路长度固定为1cm。因此不同仪器，不同批次测量的数据具有同样的可比性。
而酶标仪采用的是垂直光路, 所以光路的长度应该是液体液面的高度。所以测得的值受到样品的体积的影响。
请问BAC蛋白浓度测定波长是562，我们这边酶标仪的滤光片波长最接近的是595，这样也可以测吗
各位前辈，MTT法加样后第一天阳性组镜下看细胞全死了，样品组和阴性组镜下状态还可以，加DMSO后样品孔和阴性孔颜色粉红，阳性孔红紫到发黑，酶标仪检测，样品组和阴性组大概0.2-0.4，阳性组却有1.2-1.4，请问，这是怎么回事？细胞接板密度为4*104,100μL。向各位求助了，万分感谢！
