Background of SPANXC antibody
Human Sperm Proteins Associated with the Nucleus on X-chromosome (SPANX) are relatively low molecular weight cytoplasmic proteins found in testis and sperm. Their expression in other tissues indicates malignancies. Family members are observed as proteins that range from 15 to 20 kDa.

Western blot using SPANXC polyclonal antibody ( Cat # PAB11267 ) shows detection of a band at ~17 kDacorresponding to SPANXC present in a nuclear extract from VWM105 cells ( left panel, arrowhead ).VWM105 cells arederived from a human melanoma and arepositive for SPANX proteins.Lane 2 shows reactivity with a purified recombinant SPANXC fusion protein.The right panel shows similar reactivity with purified recombinant SPANXB, SPANXC and SPANXN proteins.Proteins were separatedby SDS-PAGE, transferred to nitrocellulose, and probed with the primary antibody diluted to 1 : 1,000.IRDyeTM800 conjugated Gt-a-Rabbit IgG [H&L] MX was used ( left ).IRDye is a trademark of LI-COR, Inc. Size estimation was made by comparison to prestained MW markers asindicated.Personal Communication. Vladimir Larionov, NIH, CCR, Bethesda, MD.
Immunohistochemistry of SPANXC polyclonal antibody ( Cat # PAB11268 ) was used at 2.5 µg/ml to detect signal in a variety of tissues including multi-human, multi-brain and multi-cancer slides.This image shows moderate positive staining of human sperm and spermatids at 60X.Tissue was formalin-fixed and paraffin embedded.The image shows localization of the antibody as the precipitated red signal, with a hematoxylin purple nuclear counterstain.Personal Communication, Tina Roush, Life Span Biosciences, Seattle, WA.

WB using Anti-SPANX (pan) antibody shows detection of a band at ~17 kDa corresponding to SPANX-C present in a nuclear extract from VWM105 cells (left panel, arrowhead). VWM105 cells are derived from a human melanoma and are positive for SPANX proteins. Lane 2 shows reactivity with a purified recombinant SPANX-C fusion protein. The right panel shows similar reactivity with purified recombinant SPANX-B, SPANX-C and SPANX-N proteins.The primary antibody was diluted to 1:1,000.
