02Verify your vial
Every vial label carries a QR code. Point your phone camera at it.
The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.
Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

Sequence
Side-chain composition
Every heavy atom is placed from the sequence with ideal bond lengths and angles, so the connectivity is exact. The pose is idealised (an extended chain) and is not a measured conformation. Identity for each lot is confirmed on its certificate.
Structure viewer04In the lab
Semax binds specific, calcium-dependent sites in basal forebrain membranes, but no receptor has been confirmed. In laboratory research it raises BDNF and TrkB activity in brain tissue and binds copper(II).

Compound
SemaxSynthetic ACTH(4-10) analog, Met-Glu-His-Phe-Pro-Gly-ProBasal forebrain
Endpoint studied
Labeled Semax bound specifically and reversibly (KD 2.4 nM); BDNF protein rose in basal forebrain at 3 h.
Dolotov 2006 · PMID 16635254Hippocampal tissue
Endpoint studied
BDNF protein rose 1.4-fold and TrkB tyrosine phosphorylation 1.6-fold; BDNF exon III mRNA rose 3-fold.

05Research history
4 milestones, each linked to its PubMed record
Biochemical and Biophysical Research Communications
Serum breakdown of ACTH(4-10) and Semax is mapped; aminopeptidases trim both, but Semax is more stable against the other enzymes.
PubMed · PMID 1851003Neuroscience Letters
In basal forebrain glial cultures, BDNF mRNA rose eight-fold and NGF mRNA five-fold 30 minutes after Semax.
PubMed · PMID 11457573Journal of Neurochemistry
Tritium-labeled Semax binds basal forebrain membranes with nanomolar affinity, and BDNF protein rises there within 3 hours.
PubMed · PMID 16635254Journal of Inorganic Biochemistry
Semax binds copper(II) in a 4N planar mode and lowers copper-induced toxicity in SH-SY5Y and RBE4 cell lines.

About Semax, its certificate and your order.
Email [email protected], Monday to Friday. A person replies within one business day.
The current released lot, SA-SMX-2611. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.
Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.
Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.
Email [email protected] within 7 days with your order number and a photo and we will replace it.
Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.
