产品说明
GoldBio growth factors are manufactured for RESEARCH USE ONLY and cannot be sold for human consumption!RecombinantHuman Family with Sequence Similarity 19 (Chemokine (C-C motif)-like), MemberA2TAFA-2FAM19A2 (TAFA-2) is chemokine-like protein containing ten cysteine residues that are conserved amongst the FAM19A (TAFA) family. This family of proteins was first identified by using a clustering algorithm on uncharacterized cDNA sequences and found to be distantly related to C-C motif chemokines, such as CCL3. FAM19A2 is expressed predominantly in the CNS, with very low expression levels detected in colon and spleen. Expression levels of FAM19A2 are highest in the occipital and frontal cortex and it is believed to be expressed constitutively. FAM19A2 is hypothesized to function as a brain-specific chemokine that regulates immune response in the CNS, as a neurokine that modulates immune response, or as a control of axonal sprouting following brain injury.Sterile Filtered White lyophilized powder. Purified and tested for use in cell culture.Source: Escherichia coliMW: ~11.2 kDa (101amino acids)Purity: >95% by SDS-PAGEand HPLC analysesBiological Activity: Fully biologicallyactive when compared to standard. The biological activity is determined by itsability to enhance neurite outgrowth of E16E18 rat embryonic corticalneurons. rHuTAFA2, immobilized at 624 μg/ml on a 96 well plate, is able tosignificantly enhance neurite outgrowth.Storage/Handling: Store desiccated at-20°C.HGNC: 21589NOT FOR HUMAN USE!Additional resources for this protein may be found at:UniProtNCBI
D-荧光素钾盐/钠盐体内使用手册--Goldbio介绍
荧光素是一种常用的荧光素酶表达的活体成像生物发光报告子。以ATP和Mg2+作为辅因子,有氧条件下荧火虫荧光素酶与水溶性底物反应发出一种特有的黄绿色发射光,在37℃活体内转换为红光。该反应通过消耗ATP来指示是否存在能量或生命的存在。
D-荧光素在生物技术领域是一种常用的试剂,尤其在活体成像方面。荧光素酶被接种在研究动物中比如大鼠,小鼠,用来标记肿瘤细胞,干细胞或传染病。通过生物荧光成像这个模式系统中D-荧光素的注射可以用来实时,非侵入性监测疾病的进程或药物效率。
