Cayman’s SARS-CoV-2 (B.1.1.7, Alpha Variant) Neutralizing Antibody SimpleDetect ELISA Kit is a competitive assay that can be used for qualitative and/or semi-quantitative measurement of neutralizing antibodies in human plasma and serum. The assay has a range of 7.81-1,000 ng/ml, with a midpoint (50% B/B0) of 100-160 ng/ml, and a sensitivity (80% B/B0) of approximately 49 ng/ml.
Innovative Research Inc Hmn Kal Rcmb Prtn C6 Htag 50UG
Human Plasma kallikrein Recombinant Protein C-6 His Tag 50UG - This protiein is recombinantly produced in Human Cells. Liquid protein buffered in 0.2 um filtered solution of 20mM TrisHCl,150mM NaCl,10% Glycerol,pH8.0. Not recommended to reconstitute to a concentration less than 100UG/ml. purity of greater than 95% determined by reducing SDS-PAGE.Endotoxin level less than 0.1 ng/ug (1 IEU/ug) determined by LAL test. Aliquot reconstituted solution to minimize freeze-thaw cycles. KLKB1 is a 638 amino acids protein that belongs to the peptidase S1 family and plasma kallikrein subfamily. It contains a peptidase S1 domain and four apple domains. The enzyme cleaves Lys-Arg and Arg-Ser bonds. It activates, in a reciprocal reaction, factor XII after its binding to a negatively charged surface. It also releases bradykinin from HMW kininogen and may also play a role in the renin-angiotensin system by converting prorenin into renin.For RUO

SMPD2 Protein LS-G15124 is a Recombinant Human SMPD2 produced in E. coli aa 2-236 with His-GST tag(s). For Research Use Only
Biotium MAP3K1 (Mitogen-Activated Protein Kinase Kinase Kinase 1)(2F6), CF647 conjugate, 0.1mg/mL
Mitogen-activated protein (MAP) kinase cascades are activated by various extracellular stimuli, including growth factors. The MEK kinases (also designated MAP kinase kinase kinases, MKKKs, MAP3Ks or MEKKs) phosphorylate and thereby activate the MEKs (also called MAP kinase kinases or MKKs), including ERK, JNK and p38. These activated MEKs in turn phosphorylate and activate the MAP kinases. The MEK kinases include Raf-1, Raf-B, Mos, MEK kinase-1, MEK kinase-2, MEK kinase-3, MEK kinase-4 and ASK 1 (MEK kinase- 5). MEK kinase-1 activates the ERK and c-Jun NH2-terminal kinase (JNK) pathways by phosphorylation of MAP2K1 and MAP2K4, and also activates the central protein kinases of the NFB pathway, CHUK and IKBKB. Additionally, MEK kinase-1 uses an E3 ligase through its PHD domain, a RING-finger-like structure, to target proteins for degradation through ubiquitination.
BioVendor, LLC Human Chorionic Gonadotropin (hCG), Native Protein (10 mg)
Human Chorionic Gonadotropin (hCG) Native Protein, 10 mg. Research use only. Bioactivity approx. 5000-6000 IU/mg. Each lot is tested for biological activity which may vary with each lot. Produced from a sterile preparation of placental glucoprotein urine of pregnant women. Total MW of 36,700 Dalton. Consists of 237 amino acids, a chain-92 a.a. and b chain-145 a.a. Sterile filtered white powder, lyophilized w/ no additives. hCG is a peptide hormone used in superovulation techniques to increase the number of ovulated oocytes in lab animals. Mice are typically injected with PMSG to stimulate follicle growth and later injected with hCG to induce ovulation. hCG is made by the embryo soon after conception and later by the syncytiotrophoblast. hCG prevents the disintegration of the corpus luteum and thereby maintains progesterone production, critical for human pregnancy. hCG may affect immune tolerance of the pregnancy. Early pregnancy testing is usually based on hCG detection/measurement.
