Background Information

The transcription factor Sp1 is a C2H2 zinc-finger protein that is involved in the regulation of a wide variety of genes, including housekeeping genes and tumor-developing genes. It is associated with tumor development, growth, and metastasis [PMID: 16209919]. It regulates the expression of a large number of genes involved in a variety of processes such as cell growth, apoptosis, differentiation and immune responses. Besides, it has a role in modulating the cellular response to DNA damage, recruiting SMARCA4/BRG1 on the c-FOS promoter, regulation of FE65 gene expression [PMID:11371615,16332679]. SP1 is detected with MW 95-105 kDa and 65 kDa in this paper(PMID: 10618488).

David (Verified Customer) (01-15-2020)

Gave a single clear band at the expected molecular weight. Low protein input was used (10µg) for experimental reasons, hence the low antibody dilution required (1:100).

• Applications: Western Blot,
• Primary Antibody Dilution: 1:100
• Cell Tissue Type: SH-SY5Y
