RhoA Antibody Datasheet

RhoA Antibody Product Information

• Immunogen: Recombinant Human RhoA protein (Catalog#12441-H07B)
• Antibody Type: Mouse Monoclonal Antibody ( Mouse mAb Service Platform )
• Clone ID: 03
• Ig Type: Mouse IgG2a
• Formulation: 0.2 μm filtered solution in PBS with 5% trehalose
• Preparation: This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human RhoA (rh RhoA; Catalog#12441-H07B; P61586-1; Met 1-Leu 193).

RhoA Antibody Usage Guide

• Specificity: Human RhoA
• Flow Cytometry:
  

  Flow cytometric analysis of Human RHOA expression in HeLa cells. The cells were treated according to manufacturer's manual (BD Pharmingen™ Cat. No. 554714), and stained with Purified Mouse anti-RHOA (12441-MM03, 1 μg/test), then a FITC-conjugated second step antibody. The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact cells.

  Flow cytometry was performed on a BD FACSCalibur flow cytometry system

• Direct ELISA: This antibody can be used at 0.5-1 μg/mL with the appropriate secondary reagents to detect Human RHOA.
• Storage: This antibody can be stored at 2℃-8℃ for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20℃ to -70℃. Preservative-Free.
  Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.

RhoA Antibody Background

Transforming protein RhoA, also known as Rho cDNA clone 12, Ras homolog gene family member A, RHOA and ARH12, is a cell membrane and cytoplasm protein which belongs to thesmall GTPase superfamily and Rho family. The Rho family of small GTPases plays a key role in the dynamic regulation of the actin cytoskeleton that underlies various important cellular functions such as shape changes, migration, and polarity. RHOA / ARH12 is part of a larger family of related proteins known as the Ras superfamily; proteins involved in the regulation and timing of cell division. RHOA / ARH12 is a small GTPase protein known to regulate the actin cytoskeleton in the formation of stress fibers. It acts upon two known effector proteins: ROCK1 (Rho-associated, coiled-coil containing protein kinase 1) and DIAPH1 (diaphanous homolog 1 (Drosophila)). RHOA / ARH12 regulates a signal transduction pathway linking plasma membrane receptors to the assembly of focal adhesions and actin stress fibers. RHOA / ARH12 serves as a target for the yopT cysteine peptidase from Yersinia pestis, vector of the plague, and Yersinia pseudotuberculosis, which causes gastrointestinal disorders. RHOA / ARH12 may be an activator of PLCE1. It is activated by ARHGEF2, which promotes the exchange of GDP for GTP.
