常见问题解答
购买多次产品,发现颜色不同,怎么办?
首先请您确认批次,如果是同一个批次产品,请联系技术同事核查产品颜色。如果是不同批次,请您放心,颜色不同可能是生产工艺不同而造成的,生产过程中的操作、温度、时间等因素可能会影响产品的颜色。如果您对该批次有疑虑,可在官网下载相应的质检报告,我们是对产品质量负责的。
如何设置母液浓度?
母液浓度需低于官网给出的溶解度,在这个范围内,根据工作液浓度设置母液浓度,细胞实验中,建议母液浓度设定在工作液浓度的 1000 倍以上。
Tween-20 可以用 Tween-80 替代吗?
不建议使用 Tween-20。相较于 Tween-20,Tween-80 的耐受性更好,Tween-80已被用作评估实验药物和毒物的行为影响的工具,且没有明显的副作用。 参考文献:Castro CA, Hogan JB, Benson KA, Shehata CW, Landauer MR. Behavioral effects of vehicles: DMSO, ethanol, Tween-20, Tween-80, and emulphor-620. Pharmacol Biochem Behav. 1995 Apr;50(4):521-6.
超声应使用什么样的频率?
频率建议使用常规的超声清洗频率即可,一般在20 kHz - 100 kHz。
溶解度写的“mg/mL”和“mM”是什么意思?
mg/mL 与 mM,是两种不同单位的表示方式,所指代的最大溶解度是一样的,可以通过官网网页下方的摩尔浓度计算器进行换算

缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
复溶方法
A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
存储
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式In general, Lyophilized powders are shipping with blue ice.
研究背景
Calreticulin is a multifunctional protein. It acts as a main Ca(2+)-binding (storage) protein in the lumen of the endoplasmic reticulum. Calreticulin binds Ca2+ ions (a second messenger in signal transduction), rendering it inactive. The Ca2+ is bound with low affinity, but high capacity, and can be released on a signal. Located in storage compartments associated with the endoplasmic reticulum, calreticulin also binds to misfolded proteins and prevents them from being exported from the endoplasmic reticulum to the golgi apparatus. The amino terminus of calreticulin interacts with the DNA-binding domain of the glucocorticoid receptor and prevents the receptor from binding to its specific glucocorticoid response element. Calreticulin reduces the binding of androgen receptor to its hormone-responsive DNA element and inhibits androgen receptor and retinoic acid receptor transcriptional activities in vivo, as well as retinoic acid-induced neuronal differentiation. Therefore, calreticulin acts as a significant modulator of the regulation of gene transcription by nuclear hormone receptors.
