CISZOG2 Antibody

What is CISZOG2 antibody and what is its target protein in plant systems?

CISZOG2 antibody is a rabbit polyclonal antibody that targets the CISZOG2 protein from Zea mays (maize). The antibody is generated against a recombinant form of the CISZOG2 protein (UniProt Number Q8RXA5). This antibody is specifically designed for plant research applications, enabling the detection and study of CISZOG2 protein expression and function in maize and potentially other plant species .

The antibody is purified using antigen affinity chromatography, which enhances its specificity for the target protein. A complete antibody package typically includes the purified antibody, pre-immune serum as a negative control, and antigen samples that serve as positive controls for validation experiments .

What validated applications exist for CISZOG2 antibody in plant research?

Based on available data, CISZOG2 antibody has been validated for two primary applications:

• Enzyme-Linked Immunosorbent Assay (ELISA): For quantitative detection and measurement of CISZOG2 protein in plant samples

• Western Blot (WB): For identification and semi-quantitative analysis of CISZOG2 protein in complex mixtures

These applications allow researchers to examine CISZOG2 expression patterns across different plant tissues, developmental stages, and experimental conditions. The antibody's specificity makes it particularly valuable for studying protein expression changes in response to various environmental stresses or genetic modifications.

What is the optimal storage and handling protocol for maintaining CISZOG2 antibody activity?

For maximum stability and retention of activity, CISZOG2 antibody should be stored at either -20°C or -80°C . The following handling protocol is recommended:
