HSP27/HSPB1 Protein, Human, Recombinant (His)

Heat shock protein beta-1 (HSPB1, also known as HSP27) is a small heat shock protein involved in many cellular processes and reportedly protects cells against oxidative stress. This protein is expressed only in insulin-dependent tissues (heart, skeletal muscle, and fat tissue), and expression of HspB7 is regulated by many different factors. HspB7 has an unusual N-terminal sequence, a conservative α-crystallin domain, and very short C-terminal domain lacking conservative IPV tripeptide involved in a small heat shock proteins oligomer formation.

Description

Species	Human
Expression System	E. coli
Tag	C-His
Accession Number	P04792
Synonyms	Hsp27, SRP27, HMN2B, HSP 27, HSPB1, CMT2F, HSP28
Construction	Recombinant Human Hsp27/HSPB1 Protein is expressed from E.coli with His tag at the C-Terminus. It contains Met1-Lys205.[Accession \|NP_001531.1]
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	The protein has a predicted MW of 23.74 kDa. The protein migrates to 25-30 kDa based on Tris-Bis PAGE result.

Endotoxin	Less than 1EU per μg by the LAL method.
Formulation	Lyophilized from 0.22μm filtered solution in PBS, 2mM DTT (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability & Storage	-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Shipping	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
