规 格  0.1ml/100μg     

纯化的抗体可通过不同的途径获取，有些磷酸化GATA结合蛋白4抗体可通过下述方法制备或从商家购买。从商家购买的抗体，通常附有正确的储存方法。

1）工作液应在4℃下融化并存放，可能稳定达数月。

2）如果没有特殊原因而避免使用叠氮钠，亦可加入叠氮钠，浓度为0．02％。将纯化的抗体样本分装成合适的体积，于-20℃保存。

3）纯化的抗体溶液应以较高的浓度(如lmg／m1)在中性pH下保存。：常用的抗体储存浓度高达l0mg/ml。较低浓度的抗体冻存前应浓缩。所有标准的浓缩方法(如超滤法)，皆可使用。还有一个简单的方法是用蛋白A或蛋白G亲和柱来浓缩溶液。如果纯化的抗体不是用于标记，可将它们以较低浓度储存于加有1％BSA的溶液中。

4）经纯化制备的抗体在常用的缓冲液中是稳定的。其DH应保持在中性左右。如果pH在7-8之间，即使保存多年，对抗体也无损害。多数情况下，盐浓度适于保持在0-150mmol/L之间，但在长期存放的抗体中，盐溶液浓度高达500mmol/L时，对磷酸化GATA结合蛋白4抗体能有损害。如果没有其他说明．律议用PBS或50mmol/LTris(DH8．0)溶液长期存放抗体。

磷酸化GATA结合蛋白4抗体产品介绍 Members of the GATA family share a conserved zinc finger DNA-binding domain and are capable of binding the WGATAR consensus sequence. GATA-1 is erythroid-specific and is responsible for the regulated transcription of erythroid genes. It is an essential component in the generation of the erythroid lineage. GATA-2 is expressed in embryonic brain and liver, HeLa and endothelial cells, as well as in erythroid cells. Studies with a modified GATA consensus sequence, AGATCTTA, have shown that GATA-2 and GATA-3 recognize this mutated consensus while GATA-1 has poor recognition of this sequence. This indicates broader regulatory capabilities of GATA-2 and GATA-3 than GATA-1. GATA-3 is highly expressed in T lymphocytes. GATA-4, GATA-5 and GATA-6 comprise a subfamily of transcription factors. Both GATA-4 and GATA-6 are found in heart, pancreas and ovary; lung and liver tissues exhibit GATA-6, but not GATA-4 expression. GATA-5 expression has been observed in differentiated heart and gut tissues and is present throughout the course of development in the heart. Although expression patterns of the various GATA transcription factors may overlap, it is not yet apparent how the GATA factors are able to discriminate in binding their appropriate target sites.

Function : Transcriptional activator. Binds to the consensus sequence 5'-AGATAG-3'. Acts as a transcriptional activator of ANF in cooperation with NKX2-5 (By similarity). Promotes cardiac myocyte enlargement.

Subunit : Interacts with ZNF260 (By similarity). Interacts with the homeobox domain of NKX2-5 through its C-terminal zinc finger. Also interacts with JARID2 which represses its ability to activate transcription of ANF. Interacts with NFATC4 and LMCD1 (By similarity). Forms a complex made of CDK9, CCNT1/cyclin-T1, EP300 and GATA4 that stimulates hypertrophy in cardiomyocytes.

Subcellular Location : Nucleus.

Post-translational modifications : Methylation at Lys-300 attenuates transcriptional activity.

DISEASE : Defects in GATA4 are the cause of atrial septal defect type 2 (ASD2) [MIM:607941]. ASD2 is a congenital heart malformation characterized by incomplete closure of the wall between the atria resulting in blood flow from the left to the right atria. ASD2 patients show other heart abnormalities including ventricular and atrioventricular septal defects, pulmonary valve thickening or insufficiency of the cardiac valves. ASD2 is not associated with defects in the cardiac conduction system or non-cardiac abnormalities.

Similarity : Contains 2 GATA-type zinc fingers.

Database links : UniProtKB/Swiss-Prot: P43694.2

GATA-4属于转录调节性因子，表达在心组织、胃肠道组织中，并调节该类T细胞的发育和功能。
