Recombinant Human Pregnancy-specific beta-1-glycoprotein 1/PSG1 is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Gln35-Pro419) of Human PSG1 fused with a polyhistidine tag at the C-terminus.
纯度
> 95 % as determined by reducing SDS-PAGE.
过滤
0.2 μm filtered
内毒素水平
Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
缓冲液
Lyophilized from a 0.2 μm filtered solution of 20 mM PB,150 mM NaCl, pH 7.4.
注意事项
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
储存条件
4 °C/-20 °C/-80 °C
储存方法
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

(Pregnancy Specific beta-1-Glycoprotein 1 (PSG1))
Pregnancy-specific beta-1-glycoprotein 1(PSBG-1 for short), also named CD66 antigen-like family member F, Fetal liver non-specific cross-reactive antigen 1/2, PSG95, Pregnancy-specific beta-1 glycoprotein C/D, is a secreted protein which belongs to the immunoglobulin superfamily, CEA family. It contains 3 Ig-like C2-type (immunoglobulin-like) domains and 1 Ig-like V-type (immunoglobulin-like) domain. The human placenta is a multihormonal endocrine organ that produces hormones, enzymes, and other molecules that support fetal survival and development.
