Kit composition:
Closure plate membrane: 2 (48) /2 (96)
Instruction: 1
Sealed bag: 1
Standard product: 0.5ml 2700ng/L * 1 0.5ml * 1 2-8
Enzyme labeled plate: 1 * 481 * 96 * 2-8
Sample dilution: 3ml * 1 ml * 1 2-8
Color reagent A solution: 3ml * 6 ml * 1 2-8
Color reagent B solution: 3ml * 6 ml * 1 2-8
Termination liquid: 3ml * 1 6ml * 1 2-8
Concentrated washing liquid: (20ml * 20) x 1 (20ml * 30) x 1 2-8
Objective: this kit is used to determine the content of serum, plasma and related liquid samples.
Operation steps:
Dilution and addition of 1 standard products:
2 samples: respectively, the blank hole (blank control hole without the sample and the enzyme label, and the remaining steps are the same), the sample hole.
3 temperature Education: 37 minutes after the closure of the sealing plate with a sealing plate.
4 with liquid: 30 (48T 20 times) the concentrated detergent liquid with distilled water 20 (48T 30 times) after dilution.
5. Washing: be careful torn off the seal plate membrane, discard liquid, drying, washing liquid to fill each hole, standing for 30 seconds after the discard, repeat 5 times, pat dry.
6 enzyme: 50 L per hole, except for the blank. 7 Wen Yu: operation with 3.
8 washing: operation with 5.
9 Color: first add color agent A50 L, and then add color B50 L, gently shake the mixture, 37 to 15 minutes.
10 termination: 50 L per hole with the end of the end of the reaction (at this time, blue).
11: Determination of the blank absorbance wavelength of 450nm zero air conditioning, in order to measure the hole (OD). Determination should be carried out within 15 minutes after the termination of the liquid.

文献和实验黑素细胞刺激素(melanocyte-stimulating hormo-ne,MSH)
两栖类垂体中间叶产生的一种激素。人类垂体中间叶退化只留痕迹。产生MSH的细胞分散在垂体前叶。有α与β两种MSH。α为13肽,β为18肽,人垂体中黑素细胞刺激素的绝大部分为β,αMSH不到3%。正常人垂体中MSH为300~400微克/克湿重,血浆中β-MSH含量约20~110微微克/毫克/毫升ml。半衰期为30分钟。MSH主要作用于黑色素细胞。体内黑色素细胞分布于皮肤及毛发、眼球虹膜色素层及视网膜色素层、软脑膜。皮肤黑色素细胞位于表皮与真皮之间,胞浆内的黑色素小体内含酪氨酸酶,可促进酪氨
PriCells: 正常人表皮黑色素细胞的培养实验材料:1. 临床活检获取的正常人皮肤材料或新生儿阴茎包皮;2. 不含Ca 2+ 和Mg 2+ 的1×PBS,添加200000IU/L青霉素、200mg/L链霉素,pH7.2;3. 黑素细胞培养液和培养基中各种添加剂的配制:包括以下种类:①胰岛素。贮存液为5mg/ml,即将0.5g的胰岛素溶于1ml 0.01mol/L的HCl液中,双蒸水加至100ml,过滤除菌、分装,-70℃下保存6个月后方可使用。使用时,在500ml培养
出现血压下降、休克、昏迷等症状,严重时可致死亡。 (二)慢性肾上腺皮质功能低下症 本病又称Addison病,乃由两侧肾上腺皮质严重破坏所致,当破坏超过90%时才出现临床症状,否则为亚临床型。发病呈隐匿性,主要症状是皮肤和粘膜以及瘢痕处的黑色素沉着增加,这是由于肾上腺皮质激素减少,促进垂体ACTH及β-LPH分泌增加,而ACTH及β-LPH在氨基酸排列顺序上有相当一部份与α或β黑色素细胞刺激素(α-MSH、β-MSH)氨基酸顺序相同,故有MSH活性(成人垂体不合成MSH),促进黑色素细胞
