Tested Applications

• Positive WB detected in: HEK-293T cells, HeLa cells, MCF-7 cells
• Positive IHC detected in: mouse testis tissue, mouse stomach tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive FC (Intra) detected in: K-562 cells

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:8000
• Immunohistochemistry (IHC): IHC : 1:50-1:500
• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.80 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

RAB13 (Ras-related protein Rab-13) is also named as GIG4. Rab13 is a member of the Rab GTPase family. RAB13 is highly expressed in malignant cells. Rab13 was highly expressed in BCSC of triple-negative breast cancer (TNBC) (PMID: 35395074). RAB13 is involved in a number of processes in LIHC, including MTORC1 signaling, MYC targets v1, G2M checkpoint, MITOTIC spindle, DNA repair, P53 pathway, glycolysis, PI3K-AKT-MTOR signaling, etc (PMID: 37803063). RAB13 enhances its circulation to the plasma membrane to promote breast cancer invasion. By influencing the tumor microenvironment, RAB13 maintains breast cancer stem cells (PMID: 37803063).
