SeqAssure™质谱验证重组蛋白：序列有确证，品质更可信

通过完整蛋白离子化、质荷比检测及多电荷峰解卷积，获得蛋白的实测分子量或分子量分布。经对比，实测分子量与理论预测高度吻合。

Measured Molecular Mass：ESI‑MS analysis of Human PTK7, His Tag (Cat. No. PT7-H52H3), showing a major peak at 76520 Da, consistent with the theoretical molecular weight.

通过肽图分析鉴定蛋白特征肽段，并将其与目标蛋白序列进行匹配，特征肽段全序列匹配，氨基酸序列覆盖率达到100%，为序列准确性提供实测证据。

Sequence Coverage Map：Human B7-1, His Tag (Cat. No. B71-H5228) was digested with trypsin and characterized by LC-MS/MS peptide mapping, achieving 100% sequence coverage.

通过 N 端测序获得蛋白起始氨基酸序列，与预期序列进行比对，精准测定 N 端起始 10-15 个氨基酸，确证蛋白表达起始无误。

N-terminal sequencing：N-terminal sequencing of Human CD117 (Cat. No. CD7-H52H4) confirmed that the experimentally determined N-terminal sequence is consistent with the theoreticalstarting sequence.
