脱盐柱工作原理:将不同物质根据分子大小进行区分。由于盐分子和样品中的目的分子(如蛋白)之间存在比较明显的大小差异,因此可以实现目的分子与盐分子的分离。

产品组分及储存条件:
| 项目号 | Component | 96T | Storage |
| P1456352A | 多肽脱盐小柱 | 96T | RT |
| H1456342A | Wash buffer 1 | 35 mL | RT |
| H1456342B | Wash buffer 2 | 24 mL | RT |
| H1456342C | Wash buffer 3 | 24 mL | RT |
| H1456342D | Elution buffer | 50 mL | RT. Store in the dark. |
| H1456342E | Loading buffer | 2 mL | RT |
| P1456352B | 收集管 | 30个 | RT |
操作流程:
①向酶解完成后的样品中加320μL的Wash buffer 1,剧烈震荡3min,15000rpm离心3min,将上层液体去除。
②将下层样品转入Tip柱中,2500rpm/min,离心3-5min,直到液体全部离心下来,如果液体流速较慢,可以加大转速。
③向脱盐柱中加入200μL的Wash buffer 2 (用之前震荡10-20s),2500rpm/min,离心3-5min,直到液体全部离心下来。
④向脱盐柱中加入200μL的Wash buffer 3,2500rpm/min,离心3-5min,直到液体全部离心下来。
⑤将脱盐柱重新放入一个新的EP管中,向脱盐柱中加入200μL的Elution buffer,2000rpm/min,离心3-5min,直到液体全部离心下来。
⑥重复步骤⑤,收集两次的洗脱液,冷冻干燥。
⑦加入10μL的Loading buffer,剧烈涡匀3min,离心20000g、10min,取适量样品,即可质谱检测。以HF-X仪器为例,上样0.5-1μg即可。
注意事项和免责说明:
1.上样过程中需保持脱盐柱中填料湿润。
2.如果样品含有高浓度的盐 (如2M尿素或者>100nM碳酸氢钠) 重复淋洗步骤1-2次。
3.该产品为一次性试用,不建议多次使用。
4.本产品仅限于专业人员的科学研究使用,不得用于临床诊断或治疗,不得用于食品或药品。
Working principle of the desalting column: It distinguishes different substances according to their molecular sizes. Due to the obvious difference in size between salt molecules and the target molecules in the sample (such as proteins), the separation of target molecules from salt molecules can be achieved.

Product Components and Storage Conditions:
| Item Number | Component | 96T | Storage |
| P1456352A | Peptide Desalting Columns | 96T | RT |
| H1456342A | Wash buffer 1 | 35 mL | RT |
| H1456342B | Wash buffer 2 | 24 mL | RT |
| H1456342C | Wash buffer 3 | 24 mL | RT |
| H1456342D | Elution buffer | 50 mL | RT. Store in the dark. |
| H1456342E | Loading buffer | 2 mL | RT |
| P1456352B | Collection Tube | 30个 | RT |
Operating Procedure:
① Add 320μL of Wash buffer 1 to the sample after enzymatic hydrolysis, shake vigorously for 3 minutes, centrifuge at 15000rpm for 3 minutes, and remove the upper liquid.
② Transfer the lower layer sample into the Tip column, centrifuge at 2500rpm for 3-5 minutes until all the liquid is centrifuged down. If the liquid flow rate is slow, the rotation speed can be increased.
③ Add 200μL of Wash buffer 2 (shake for 10-20 seconds before use) to the desalting column, centrifuge at 2500rpm for 3-5 minutes until all the liquid is centrifuged down.
④ Add 200μL of Wash buffer 3 to the desalting column, centrifuge at 2500rpm for 3-5 minutes until all the liquid is centrifuged down.
⑤ Put the desalting column into a new EP tube, add 200μL of Elution buffer to the desalting column, centrifuge at 2000rpm for 3-5 minutes until all the liquid is centrifuged down.
⑥ Repeat step ⑤, collect the eluates from both times, and freeze-dry them.
⑦ Add 10μL of Loading buffer, vortex vigorously for 3 minutes, centrifuge at 20000g for 10 minutes, take an appropriate amount of sample for mass spectrometry detection. Taking the HF-X instrument as an example, 0.5-1μg of sample is sufficient for loading.
Precautions and Disclaimer:
1.During the sample loading process, the packing in the desalting column must be kept moist.
2.If the sample contains a high concentration of salt (such as 2M urea or >100nM sodium bicarbonate), repeat the rinsing step 1-2 times.
3.This product is for one-time use only; multiple uses are not recommended.
4.This product is limited to scientific research use by professional personnel, and must not be used for clinical diagnosis or treatment, nor for food or drugs.
