Human RYBP Baculovirus-Insect cells Overexpression Lysate: 产品信息
This Human RYBP overexpression lysate was created in Baculovirus-Insect cells and intented for use as a Western blot (WB) positive control. Purification of RYBP protein (Cat: 14292-H20B) from the overexpression lysate was verified.
A DNA sequence encoding the human RYBP (Q8N488) (Met1-Phe228) was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.
The recombinant human RYBP /GST chimera consists of 465 amino acids and has a calculated molecular mass of 52.6 kDa. The recombinant protein migrates as an approximately 58 kDa band in SDS-PAGE under reducing conditions.
Human RYBP Baculovirus-Insect cells Overexpression Lysate: 使用指南
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.
2. Re-dissolve the pellet using 200μL pure water and boil for 2-5 min.
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
稳定性 & 储存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
Western Blot (WB) Optimal dilutions/concentrations should be determined by the end user.

APAP-1, also known as AAP1 and RYBP, is widely expressed. It is highest expressed in lymphoid tissues and placenta. APAP-1 contains 1 RanBP2-type zinc finger. It may bind to DNA. APAP-1 inhibits ubiquitination and subsequent degradation of TP53, and thereby plays a role in regulating transcription of TP53 target genes. It may be implicated in the regulation of the transcription as a repressor of the transcriptional activity of E4TF1. APAP-1 also promotes apoptosis.
