SPESP1 Protein, Human, Recombinant (His)

Catalog No. TMPJ-01190
Synonyms: Sperm Equatorial Segment Protein 1, Glycosylated 38 kDa Sperm Protein C-7/8, ESP, SP-ESP, SPESP1, Equatorial Segment Protein

Sperm Equatorial Segment Protein 1 (SPESP1) is a member of the SPESP1 family. SPESP1 is highly expressed in the testis, where it is localized to the acrosome of postmeiotic stages of spermiogenesis; it is expressed at lower levels in the placenta and fetal lung. SPESP1 is involved in the multicellular organisimal development. Disruption of SPESP1 leads to abnormal distribution of sperm proteins resulting in a detached membrane from the equatorial segment and less fertile sperm. SPESP1 may interact with IZUMO1 and MN9 antigen and it contains an N-glycosylation site as well as several cAMP-dependent kinase, protein kinase C, and casein kinase II consensus phosphorylation sites.

Construction Recombinant Human Sperm Equatorial Segment Protein 1 is produced by our Mammalian expression system and the target gene encoding Tyr20-Tyr350 is expressed with a 6His tag at the C-terminus.
Protein Purity Greater than 90% as determined by reducing SDS-PAGE. (QC verified)
Molecular Weight 58 KDa, reducing conditions
Endotoxin Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Formulation Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
Reconstitution Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 
Stability & Storage

Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.

Shipping

The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
