d********0 发帖数: 202 | 2 今天收到这个offer,请教各位值么?之前已经有过白金卡了
一些想法:
1.白金的200到airline fee买西南的egc应该没有问题吧,毕竟可以买任何数量的,精
确到小数点后两位,Amex应该看不出来
2.Uber用的不多,但是这个至少不会短时间内过期
3.60k MR肯定比550-200-200的年费值,但是同时失去了未来一年PRG在菜店MS的收益,
姑且算每个月MS1万刀
4.马上12月了,来得及把今年的200刀air fee消费掉么?收到卡应该很快吧?
5.准备1月份申请Amex Hilton 的白金卡,会不会有影响?
多谢各位! |

不计便携现在比较流行的是Beholder MS1 Gimbal配GH4或A7系列. 当然这套下来都三四

两重串联Mass 乃至傅立叶变换 三重串联Mass 和传统Mass的分析蛋白质的区别是
后者只有分子量的定性 和相对稳定同位素标示后的比如 SILAC Mass的定量
而前者 可以测 wild pH (NH4)2 SO4 溶液 pH 6.9 中的蛋白 二级结构 数据 乃至

K******S 发帖数: 10109 | 16 4倍的变化用LabelFree没有问题,我说的Subtle变化是指50%以下。
关于Ms定量的问题,不同的Peptide是不能比较的,因为序列不同会造成离子化的不同
,但是同样的Peptide在不同样品里是可以比较的。
现在Label Free有2个大的方向,1是Spectral Counting (MS2 Based),2是MS1
Based的那HPLC的峰面积来定量,我个人倾向于第2种,因为更准确。一般的HPLC定量用
Uv做Detector,LCMSMS只不过是用Ms做Detector。
当然这些都基于最近的仪器发展,现在Lc和Ms都是High Resolution了,所以一般的
Label Free没有问题。 |
|
l****y 发帖数: 398 | 17 我觉得趋势就是上面有人说的,同一个run里, 既做MS1,也做MS2;然后用MS2里几个
比较干净的fragment 的 XIC 来定量. 这要求每个peptide被MS2次数足够多,这样XIC
才有足够多的点来define一个峰。
现在机器比较慢,为了让更多不同的peptide被MS2, 人为的用dynamic exclusion减少
同一个peptide被重复MS2的次数;但也造成没法用fragment 的XIC来定量。
所以未来速度比较快的tof仪器应该会重新流行。 |

K******S 发帖数: 10109 | 18 TIC is meaningless. You can probably ignore your 1st figure.
2nd figure (sounds like MS1), you need to zoom in the area where you detect
the intact peptides, for high resolution data, you need to show all the
isotopic peaks and at least 4 decimals of m/z, such as 1000.0000 (assuming
you use high resolution instrument)
3rd figure you mentioned sounds like MS2 spectra, did you label the
fragments? |

h*****s 发帖数: 153 | 21 对比amount还是找新蛋白?label free一般都是要不比较MS1 intensity,要不MS2
spectral counts。
还有,你前期不simplify样品,很多peptide会测不出来吧,全都ion suppression了,
还是,你用了很多salt cycle? |
|
K******S 发帖数: 10109 | 22 ETD sensitivity/efficiency比CID低是肯定的
CID在ION TRAP里还是最快的
FUSION叫TRIBRID是你可以同时做3件事情.我觉得如何利用这个优势更重要.比如在
ORBITRAP做MS1或者HCD的时候别让ION TRAP闲着.
CID FRAGMENT的时候是M/Z FOCUS的,意味着如果PEPTIDE上的修饰容易掉的话,就不会有
很好的BACKBONE FRAGMENTS (因为修饰掉了M/Z就变了), ETD可以解决这个. 但现在有
HCD了,是QUADRUPOLE FRAGMENTATION (修饰掉了还可以继续FRAGMENTATION),对修饰的
PEPTIDE效果也不错.
尤其FUSION的速度太快了,15HZ ORBITRAP, 20HZ ION TRAP. 那这个当QE使唤有些大材
小用了. |
|
k****o 发帖数: 728 | 23 如果你的peptide比较长,以至于产生很多+3--+5甚至更高的fragment ions,那么无论
对于ETD还是CID,在OT里做high resolution的MS2都更有利。而ETD是有利于high
charge state,long peptide的fragmentation。所以,如果你的样品确实有很多long
peptide的话(你去raw data file,average一段MS1的data就有底了),用OT scan
MS2会让搜索效果更好。你搜索时记得把fragment ions的error window舍得很窄,这样
才起到high resolution的效果。比如10 or 20ppm,或者0.01 m/z,取决于你具体的
accuracy。你可以试试MS2用15000 resolution with 20 ppm error window。
关于省时间的问题。诚然IT确实比OT省时间,如果你用老一代的LTQ Orbitrap,这个确
实是个大concern。但技术在进步,Orbitrap Fusion已经在设计上提供了比过去快得多

b*******g 发帖数: 1309 | 28 pulse的频率很高,20k Hz, 每个pulse的时间是0.05ms, inter pluse是包含在0.05ms
之内的
TOF 的pluse pusher不是问题的关键。
一个spectrum 是若干个pluse 累加的,完成一个spectrum过后需要的传输时间很长,
至少在2ms以上。 在传输data前,即使有离子进入detector 也不会被记录的。
甚至仪器在做MS/MS的时候,还有一个 “thinking time”,在50ms level per (MS1+
nMS2) cycle。这些都是造成离子不能被检测到时间。
Trap的accumulation 跟trap 可以在1-10ms完成,对于特别低浓度的可以trap 100ms以
上。 但是检测时间比较长,在50-100ms level,甚至更长。

y*****s 发帖数: 1047 | 29 pulse ON时间通过的离子会进入reflectron被检测,而inter pulse或者说pulse OFF时
间通过的离子不能进入reflectron不被检测,这个比例有多少?和频率高低无关,但是
对灵敏度很重要
如果数据传输速度不够快,那么被记录的数据占总数据的比例又是多少?0.05ms/50ms?
这个跟dwell time或者频率有关,而且对灵敏度很重要
如果trap扫描的时间是收集离子时间的十倍,那么跟QqQ比离子利用的效率只有不到1/
10了
但是如linear trap,容量比较大,可以把收集离子的时间提高到多少呢?
