easYmer HLA-B*14:01 MHC Tetramers Kit
easYmer HLA-B*14:01 MHC Tetramers Developed and Manufactured by immunAware
Materials Included:
The easYmer kit contains a peptide receptive preparation of HLA, a folding buffer, a positive control peptide for HLA-complex folding. The exact identities of these components are given below:
- easYmer: HLA-B*14:01 (C67S; unpaired Cysteine in position 67 is substituted for Serine) – peptide receptive, biotinylated in Tris/Maleate pH 7 with 30% Glycerol
- Folding Buffer: Tris/Maleate pH7
- Peptide: RRYTRRISL, a stable HLA-B*14:01 binder. Positive control for evaluation analysis of peptide-HLA folding.
for Research Use Only
Available Sizes:

Assay Principle
This easYmer HLA-B*14:01 MHC Tetramers protocol is designed to evaluate the efficiency of peptide-HLA-I interaction and complex formation. The assay is based on detecting the ß2-microglobulin (ß2m? light chain subunit of recombinant HLA Class I (HLA-I) comlexes, where the heavy chain has been biotin tagged. These tagged complexes are subsequently captured by streptavidin coated beads, labeled with PE-conjugated anti-human ß2m, and analyzed by flow cytometry. Since peptide-HLA-I complex formation is entirely peptide dependent, bead-associated signals will only be detected if the peptide in question supports the folding of the HLA-I allotype of interest; peptides that efficiently support folding will give strong signals whereas peptides that support folding sub-optimally, or not at all, will give moderate to non-detectable signals.

女患，70岁，大专毕业，我院退休药师。7-8年前患脑梗（具体不详）。记忆力差5-6年，近记忆为著，几次做饭后忘记关火，将炉具的台板（玻璃的）烧裂。近5-6年来，病人每年住院彻底检查治疗1次（主要是使用活血化瘀及营养脑细胞药）。平素，病人双耳听力略差，睡眠欠佳、便秘、尿频，偶从卧位坐起时视蒙。既往有时血压略高，未降压治疗。本次为“通血管”再来住院。查体：血压：140/80mmHg,双耳听力略差，近记忆力差，但智力（MMSE：26分)正常，颅神经未见异常，四肢肌力、感觉未见异常，植物神经未查，双掌颌反射（+），双下肢病理反射均阴性。血常规：淋巴细胞比率略高，余均正常；尿常规、心电图、癌胚抗原均正常；凝血四项：除凝血酶时间略长外均正常；生化全项：除总胆固醇略高外均正常；超声心动图：老年瓣退行性改变，左室舒张功能减退，房膜瘤可能。彩超：双侧颈动脉粥样硬化形成。头MRA:右大脑中动脉及其分支未显示。
问题：1MRI怎么会这样逍遥？病人无肢体瘫，生活自理如常人。
2为明确头MRA:右大脑中动脉及其分支未显示的病因和程度，除做DSA外，还需做什么？
3如不做DSA，给他订类药、阿斯匹林及活血化瘀的中药可不可以？
教。
