Preparation and Storage
Avoid repeated freeze/thaw cycles. Store at 2-8 degree C for one month. Aliquot and store at -80 degree C for 12 months.
Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is lessthan 5% within the expiration date under appropriate storage condition.

NCBI Description

The correlation of anti-sperm antibodies with cases of unexplained infertility implicates a role for these antibodies in blocking fertilization. Improved diagnosis and treatment of immunologic infertility, as well as identification of proteins for targeted contraception, are dependent on the identification and characterization of relevant sperm antigens. The protein expressed by this gene is recognized by anti-sperm agglutinating antibodies from an infertile woman. Furthermore, immunization of female rats with the recombinant human protein reduced fertility. This protein localizes to the plasma membrane of germ cells in the testis and to the post-acrosomal plasma membrane of mature spermatozoa. Recombinant polypeptide binds GTP and exhibits GTPase activity. Thus, this protein may regulate GTP signal transduction pathways involved in spermatogenesis and fertilization. Two transcript variants of this gene encode the same protein. [provided by RefSeq, Jul 2008]

Product Notes

The SPAG1 spag1 (Catalog #AAA2033218) is a Recombinant Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Sperm Associated Antigen 1 can be used in a range of immunoassay formats including, but not limited to, SDS-PAGE, Western (WB), ELISA (EIA), Immunoprecipitation (IP). Researchers should empirically determine the suitability of the SPAG1 spag1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: MTTKDYPSLW GFGTTKTFKI PIEHLDFKYI EKCSDVKHLE KILCVLRSGE EGYYPELTEF CEKHLQALAP ESRALRKDKP AATAASFTAE EWEKIDGDIK SWVSEIKKEE DKMHFHETET FPAMKDNLPP VRGSNSCLHV GKEKYSKRPT KKKTPRDYAE WDKFDVEKEC LKIDEDYKEK TVIDKSHLSK IETRIDTAGL TEKEKDFLAT REKEKGNEAF NSGDYEEAVM YYTRSISALP TVVAYNNRAQ AEIKLQNWNS AFQDCEKVLE LEPGNVKALL RRATTYKHQN KLREATEDLS KVLDVEPDND LAKKTLSEVE RDLKNSEAAS ETQTKGKRMV IQEIENSEDE EGKSGRKHED GGGDK. It is sometimes possible for the material contained within the vial of "Sperm Associated Antigen 1, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
