產品描述：

人胱硫醚β-合酶(CBS)酶聯免疫試劑盒（CSB-E13314h）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、細胞裂解物樣本中的CBS含量。人胱硫醚β-合酶（CBS）是轉硫途徑中的關鍵酶，參與同型半胱氨酸（Hcy）的代謝，其活性與心血管疾病風險相關。研究顯示，CBS在Hcy轉化為胱硫醚的轉硫酸路徑中起重要作用，其表達上調與多種疾病如唐氏綜合癥和癌癥有關。抑制CBS可能對治療這些疾病有益。試劑盒檢測范圍為125 pg/mL-8000 pg/mL，適用于研究CBS在細胞代謝調控、氧化應激響應及疾病模型中的表達變化，也可用于評估藥物或基因干預對CBS活性的影響，為探究相關疾病的分子機制提供可靠工具。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

精密度：

Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of human CBS in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:1	Average %	94
	Range %	90-98
1:2	Average %	106
	Range %	102-110
1:4	Average %	96
	Range %	90-101
1:8	Average %	88
	Range %	86-96

回收率：

The recovery of human CBS spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	103	98-106
EDTA plasma (n=4)	94	91-97

產品評價

靶點詳情

功能：

Hydro-lyase catalyzing the first step of the transsulfuration pathway, where the hydroxyl group of L-serine is displaced by L-homocysteine in a beta-replacement reaction to form L-cystathionine, the precursor of L-cysteine. This catabolic route allows the elimination of L-methionine and the toxic metabolite L-homocysteine. Also involved in the production of hydrogen sulfide, a gasotransmitter with signaling and cytoprotective effects on neurons.
