【预期用途】

用于待测致敏红细胞样本的预处理，使致敏红细胞样本中的待测抗体从与细胞结合的状态中解离释放出来。以便于使用体外诊断试剂或仪器对待测抗体进行检测。

【检验原理】

红细胞上的抗原与血清中抗体在适合条件下发生致敏，这种结合在一定条件下是可逆的。将已致敏的红细胞悬浮于低pH值的甘氨酸溶液中，抗体蛋白又可以从结合的红细胞上解离释放出来。离心取上清解离的放散液，此液中含有从红细胞表面解离释放出来的抗体蛋白，经Tris缓冲液调节pH至中性后此上清放散液可用于相关抗体的检测和鉴定；而解离释放后的红细胞经洗涤后可用于血型定型、自身抗体的吸收等。

【主要组成成份】

1.溶液I：主要组分为甘氨酸(C₂H₅NO₂)，氯化钠(NaCl)。

2.溶液II：主要组分为Tris碱，指示剂。   

【储存条件及有效期】                  

常温（10～30℃）储存，有效期1年。试剂开瓶后在常温（10～30℃）条件下可储存6个月。

【样本要求】

新鲜或2～8℃保存不超过72小时的抗凝血样。

例如，天冬氨酸和精氨酸的混合物置于电泳支持介质(滤纸或凝胶)中央，调节溶液的pH至6.02(为缓冲溶液)时，此时天冬氨酸(pI=2．98)带负电荷，在电场中向正极移动，而精氨酸(pI=10.76)带正电荷，向负极移动解离原则：先解离α-COOH，随后其他-COOH；然后解离α-NH3+，随后其他-NH3。总之羧基解离度大于氨基，α-C上基团大于非α-C上同一基团的解离度。等电点的计算：首先写出解离方程，两性离子左右两端的表观解离常数的对数的算术平均值。一般pI值等于两个相近pK值之和的一半。如天冬氨酸 赖氨酸。[2] 
4、氨基酸的酸碱滴定曲线
以甘氨酸为例：摩尔甘氨酸溶于水时，溶液pH为5.97，分别用标准NaOH和HCl滴定，以溶液pH值为纵坐标，加入HCl和NaOH的摩尔数为横坐标作图，得到滴定曲线。该曲线一个十分重要的特点就是在pH=2.34和pH=9.60处有两个拐点，分别为其pK1和pK2。 规律：pH<pK1′时,[R]>[R±]>[R]; pH>pK2′时，[R]>[R±]>[R+]; pH=pI时，净电荷为零，[R]=[R-]; pH<pI时，净电荷为“+”； pH>pI时，净电荷为“-”。 
密码子（codonm），RNA分子中每相邻的三个核苷酸编成一组，在蛋白质合成时，代表某一种氨基酸。科学家已经发现，信使RNA在细胞中能决定蛋白质分子中的氨基酸种类和排列次序。也就是说，信使RNA分子中的四种核苷酸(碱基)的序列能决定蛋白质分子中的20种氨基酸的序列。碱基数目与氨基酸种类、数目的对应关系是怎样的呢？为了确定这种关系，研究人员在试管中加入一个有120个碱基的信使RNA分子和合成蛋白质所需的一切物质，结果产生出一个含40个氨基酸的多肽分子。可见，信使RNA分子上的三个碱基能决定一个氨基酸。组成蛋白质的大部分氨基酸是以埃姆登-迈耶霍夫（Embden－Meyerhof）途径与柠檬酸循环的中间物为碳链骨架生物合成的。
For example, a mixture of aspartic acid and arginine is placed centrally in an electrophoresis support medium (filter paper or gel) and the pH of the solution is adjusted to 6.02 (buffer) when aspartic acid (pI = 2.98 ) Is negatively charged and moves toward the positive electrode in the electric field, whereas arginine (pI = 10.76) is positively charged and moves to the negative. The principle of dissociation is that dissociation of α-COOH followed by other -COOH and then dissociation of α-NH3 + , Followed by -NH3. In general, the degree of carboxyl group dissociation is greater than the amino group, and the α-C group is larger than the dissociation degree of the same group on the non-α-C. Calculation of isoelectric point: First, write out the arithmetic mean of the logarithm of the apparent dissociation constants at the left and right ends of the zwitterion solution equation. The normal pI value is equal to half the sum of two similar pK values. Aspartate lysine. [2] 
4, acid-base titration curve of amino acids
Taking glycine as an example: When the molar glycine is dissolved in water, the pH of the solution is 5.97, titrated with standard NaOH and HCl respectively, and the pH value of the solution is taken as the ordinate. The moles of HCl and NaOH are plotted on the abscissa to obtain the titration curve. A very important feature of this curve is that it has two inflection points at pH = 2.34 and pH = 9.60, which are its pK1 and pK2, respectively. [R]> [R ±]> [R +]; at pH = pI, the net charge is zero when Rp> R [R] [R] = [R-]; the net charge is "+" at pH <pI; and the net charge is "-" at pH> pI.
Codonm, a group of three adjacent nucleotides in an RNA molecule, representing a certain amino acid when the protein is synthesized. Scientists have found that messenger RNA can determine the type and order of amino acids in a protein molecule in a cell. That is, the sequence of four nucleotides (bases) in a messenger RNA molecule determines the sequence of 20 amino acids in a protein molecule. What is the correspondence between the number of bases and the number and type of amino acids? To determine the relationship, the researchers added a 120-base messenger RNA molecule and everything needed to synthesize the protein in the test tube, resulting in a 40-amino acid peptide. Can be seen that three bases on messenger RNA molecules can determine an amino acid. Most of the amino acids that make up the protein are biosynthesized into a carbon chain backbone by the Embden-Meyerhof route to the citric acid cycle intermediates. The exception is the aromatic amino acid, histidine, the former biosynthesis of pentose phosphate intermediates erythrose 4-phosphate, which is synthesized by the ATP and phosphoribosyl pyrophosphate. Microorganisms and plants can synthesize all the amino acids in the body, and some of the animal's amino acids can not be synthesized in the body (essential amino acids).
